Compression Latch: Everything You Need to Know

Door Lock Buying Guide

The majority of deadbolt locks tested by Consumer Reports do not provide the necessary level of protection that may be expected. In our testing facility, it only takes a few strategic kicks or a few minutes of being attacked with a cordless drill to defeat almost every lock in our ratings. This applies to both traditional deadbolts and modern electronic and smart locks, which can be controlled via smartphone, smartwatch, or smart speaker.

Door Lock Types

The three main categories of door locks available today include conventional, nonconnected deadbolts, smart locks, and retrofit smart locks. Gain a better understanding of these options with the following information.

Smart Locks

Some smart locks come with additional features such as remote control, voice control, access logs, and geofencing. Keep in mind that these features may require a separate WiFi adapter or bridge, which can add to the cost. However, newer models often have built-in WiFi for convenience. You can also opt for Bluetooth-only smart locks, which have a limited wireless range but still offer some smart features.

Pros: These models offer both convenience and added peace of mind, especially when equipped with optional WiFi connectivity, allowing for remote control and other intelligent features..

Cons: Connected locks are as vulnerable to forced entry as nonconnected locks and are also at risk of digital hacks. These models may require additional hardware (often sold separately) for remote capabilities and are typically more costly than traditional deadbolt locks. Additionally, Bluetooth-only models may have a limited range for their remote features.

Conventional and Electronic Door Locks

While these models may not have extravagant features, they excel at securing your doors. These options range from high-end, drillproof models from Medeco to budget-friendly deadbolts found in many stores, as well as electronic models with keypads for PIN programming. Most are single-cylinder locks, and some can be easily rekeyed without the expense of a locksmith.

Pros: The models available are both cost-effective and can be easily rekeyed. When compared to key-in-knob locks, deadbolts greatly enhance the level of security. With electronic locks, you have the ability to lock and unlock your door without needing a physical key..

Cons: They lack the convenience and extra features of smart models.

Retrofit Smart Locks

These models provide the same features as traditional smart locks, except they replace only a portion of your current deadbolt (typically the interior portion with the thumb-turn). This allows you to keep your original deadbolt and keys while gaining smart capabilities like remote control and automatic unlocking. Additionally, several retrofit smart locks come with wireless keypads for pin entry, though they are often sold separately.

Pros: Preserve your current keys and exterior deadbolt while ensuring it matches the front door handle set.

Cons: The effectiveness of these smart locks is largely influenced by the strength of your current deadbolt. If it is vulnerable to forceful entry techniques such as kicking, drilling, or picking, the smart features may be rendered ineffective in preventing intruders.

Compression Latch - Complete Product Guide

When it comes to sealing tightly against dust and moisture, a compression latch is essential for enclosures such as electrical enclosures, telecom lockers, or cooling chambers. Latches are great mechanical devices for keeping doors or similar surfaces closed, but for a secure seal, a compression latch is the way to go.

In this guide, we will delve into the topic of compression latches. We will cover their definition, functionality, various types, and their suitable uses. Furthermore, we will touch upon the process of installing them and where they can be obtained when necessary.

What is a Compression Latch?

In its various forms, a compression latch utilizes both a base and a cam lever, functioning similarly to a traditional cam latch. However, what sets it apart is its ability to compress gaskets against doors and panels upon closing, creating a strong seal. This makes it ideal for fulfilling specific environmental needs such as protection against moisture, rain, water, dust, and even vibration and electrical interference.

Compression lathes, like regular cam latches, may include a T-handle or lock for added security. There are two main types of compression latches: fixed latches with fixed cams for consistent compression, and adjustable latches that function like adjustable cam latches. The latter can also be adjusted for varying levels of compression and decompression.

How Does a Compression Latch Work?

Compression latches operate using the same concept as standard quarter-turn cam latches. They are a dependable option for securing doors and panels and providing defense against water, dust, vibration, and electromagnetic interference in enclosures that demand these safeguards.

Use any of the following quick-action fastening devices - a key, a cam lever, a T-handle, or another type of device - to adjust the base of the compression latch. This applies consistent force to the gasket around the enclosure opening, effectively closing all gaps that could potentially allow dirt, water, or insects to enter.

The two variations of compression latches cater to different applications. If dealing with heavy-duty tasks, opt for a compression toggle latch, with its strong latching force and low operating effort. For moderate and lighter tasks, a standard latch with a handle, button, or key locking is sufficient, as smaller amounts of compression are needed.

A recommended method for accurate and efficient installations is using compression latches with a non-adjustable cam, often considered the optimal solution. These latches do not need to be adjusted and cause minimal interference with the sealed area.

For applications with large differences, the use of adjustable compression latches is necessary. These latches can be adjusted to suit the specific application and desired level of compression, providing flexibility for different tolerances and reducing the need for constant management and maintenance, resulting in cost savings.

The aspect of accessibility should be taken into account when selecting enclosures. Those that are commonly accessed by hand would typically need non-locking latches with T-handles, knobs, or levers like flush triggers for their mechanisms.

When ensuring secure environments, access may need to be restricted to authorized personnel only. This could include the use of specialized compression latches with locking mechanisms that require keys or specific tools for operation.

Compression Latch Benefits

When it comes to protecting against water, using compression latches has numerous advantages, especially in specific applications. These include electrical enclosures, telecom equipment lockers, industrial generators, and HVAC system components, all of which share the common sensitivities of being affected by elements and causing vibrations and noise.

To minimize vibration and noise in industrial machines, a compression latch with a protective gasket between the door and opening panel is recommended. This prevents vibrations from transferring to the enclosure and reduces overall noise levels by absorbing and neutralizing vibrations.

The merchant also provides instructions for sealing out dust, water, and moisture from the environment using compression latches. This is especially useful for protecting electrical machines and telecom equipment, which are typically sensitive to these elements.

Industrial latches are commonly constructed from stainless steel or black powder-coated zinc alloy, resulting in an IP65 rating for dust and rain resistance.

When protecting equipment, it is important to ensure that only authorized personnel have access. To achieve this, use a latch that can be secured with a padlock or a compression cam lock. These types of locks require keys or specialized tools for operation, making them effective at preventing unauthorized access.

One additional advantage of compression latches is their easy installation process, which is comparable to that of regular cam latches. Basic tools, such as a drill, screwdriver, washers, screws, or rivets, and approximately 15 minutes are all that is required. If needed, feel free to ask for assistance from someone with experience.

When installing adjustable compression latches, it may be necessary to make minor adjustments after mounting to achieve the desired compression. Keep in mind that gaskets, while simple to install and replace, can lose their elasticity and shape over time. Fortunately, adjustable cam locks offer the flexibility to adjust the compression as needed.

Installation

It is crucial to follow specific steps for maximum efficiency when using our compression latch.:

1.Be sure to choose an installation cutout that matches the dimensions of the lock. If the cutout is too large, the latch may not work effectively, and if it's too small, you won't be able to install the latch. It's also important to know the thickness of the door or panel before purchasing a fixed compression latch, as adjustable latches can adjust for varying thicknesses.

2.Selecting materials for your latch is an important step after choosing the installation cutout. Available options include zinc alloys, stainless steel, and chrome- and zinc-plated metals. Additionally, consider the body type of your latch, such as handle and lever latches, as well as low-profile choices like trigger latches, raised triggers, and push latches.

3.Choose the type of key you prefer when selecting a compression latch lock. The most common key types are rounded, tubular, and flat, while others may choose cylinder or hex keys.

4.There are various accessories to choose from, depending on the type of locking mechanism or handle. These accessories include dust caps, finger pulls, fasteners, inserts, spacers, and adapters.

How to Choose a Door Lock

Here is a simple step-by-step guide to choosing the right door lock for your home.

1. Learn Lock Lingo

The tested deadbolts, whether conventional or smart, are generally operated via a key (or keypad and PIN) from the outside, or a thumb-turn from inside. The more secure options possess hardened cylinders, unique PIN configurations, and other protective measures. Our ratings align with the industry rankings, which range from Grades 1 to 3, with Grade 1 locks being the most difficult to disable. However, this information may not always be displayed on the packaging, so it may be necessary to visit a company's website to determine a lock's rating.

2. Decide How Much You Can Spend

Consider investing in a high-quality lock, such as one from Medeco, or a smart lock, despite their initial expense. In the event of a break-in, the cost of the lock may be less than your insurance deductible. Additionally, many insurance policies offer discounts for homes equipped with deadbolts.

3. Determine Whether You Want a Smart Lock

Discover the convenience a smart lock offers for busy individuals. Don't be put off by the price - consider the peace of mind it provides for forgetting to lock your door or when letting in workers or pet sitters during your absence. It can also assist in monitoring your children's arrival from school.

Smart locks offer a solution to these issues through the use of smartphone applications and the option for remote locking and unlocking capabilities. Keep in mind that some form of WiFi bridge may be necessary for remote access, which could come at an additional cost. However, many smart locks now come with built-in WiFi, as the technology has become more energy-efficient over time. If you're interested in a smart lock but don't want to pay extra for WiFi access, consider an electronic lock, which provides keypad access and the ability to assign and share PINs with various guests, but does not have the ability to communicate with your smartphone.

4. Beef Up the Doorframe and Lock

Ensure the safety of your doors by reinforcing them with a heavy-duty metal box strike and 3-inch screws. This will prevent weak or hollow-core doors from giving way, even when faced with a strong lock. For added security, consider using 3-inch screws on your existing strike plate and securing hinges with the same size screws. Always follow the manufacturer's instructions for installation.

Consider not purchasing a double-sided lock. Some towns view them as a fire hazard because unlocking the door from the inside requires a key, resulting in the risk of being locked in. However, these locks can provide a sense of security when placed on a door next to glass sidelites, preventing burglars from breaking the glass and using a thumb-turn to unlock the door.

Latest Trends in Smart Locks

Although door locks typically do not undergo significant change compared to products like appliances and electronics, the advent of smart locks has brought about several advancements in recent times.

Recent advancements in internet-connected smart locks have brought about significant improvements. Now, numerous models are capable of connecting directly to WiFi, eliminating the necessity for hubs and bridges for internet connectivity. Additionally, some smart locks even offer fingerprint sensors as a convenient alternative to traditional unlocking methods.
