5 Questions About Compression Latches

Consumers often miss compression locks and other touch-point solutions, yet they’re important to the application. Compression locks can improve an industrial product’s performance, ergonomics, and security How can you know which compression-latching product is best for a project? Here are five questions to ask while buying a compression latch:

  1. What Are The App Requirements?

Compression latches can hold doors and panels shut while reducing noise, panel movement, and rattling. They can compress a gasket to seal out water, dust, and EMI. To choose the right latch, determine how much compression is needed. Different applications demand different levels of compression depending on vibrational forces or gasket size. Heavy-duty applications may require lever latches, which provide a mechanical advantage with stronger latching forces and lesser user effort. A compression latch with a fixed grip is frequently suitable for precision and speed. A fixed grip requires no adjustment during installation and provides little intrusion.

  1. How Is The Compression Latch Used?

This is vital when choosing a latch’s material, strength, and construction. Determine the latch’s use. A latch may be opened and closed multiple times a day for years. If so, a provider must validate the latch’s long-term function. Consider the force the latch must withstand during normal operation or unexpected circumstances, which may indicate it should be composed of zinc or stainless steel. The environment might also challenge a latch. Exterior applications may need to endure sun, wind, or cleaning agents. Such considerations can identify the best material for weatherproofing. Sealing against moisture, rain, or water spray might lead to varied latch sealing alternatives to protect the enclosure interior.

  1. How Is The Latch Installed?

In many circumstances, the perfect compression latch must suit a precise design footprint. For a restricted mounting area, a smaller compression latch with one mounting hole may be appropriate. When choosing a compression latch, consider the panel thickness. When choosing a compression latch, consider the application’s internal space. If inside space is limited, an external latch can be used to minimize intrusion. A flush-mounted or recessed latch reduces the chance of clothing or undesirable items catching on it.

  1. What Are Ergonomic And Security Needs?

How is the latch panel opened and closed? How is the latch used? Is there a separate handle to open the enclosure? These are crucial questions when choosing a compression latch. Pressing a button, lifting and turning a handle, moving a knob, or spinning a tool can open compression locks. For latches that are accessible by hand often, a T-handle or knob may be chosen. These are also useful if the user is wearing gloves.

In secure environments, authorized employees may be needed. There are additional security solutions beyond a simple compression latch. Latches requiring specific tools may limit opening. For restricted areas, such as pharmaceutical storage lockers, key locking alternatives can limit access to those with the correct key, reducing theft and damage.

  1. What Else Affects Compression Latch Selection?

Environmental and security concerns are usually the most essential reasons for selecting a compression latch system, although aesthetic needs may also be important. As consumers increasingly value aesthetics, evaluate the final product’s appearance. End-users can see the latch? If so, does it meet aesthetic standards? These inquiries might assist define the material and finish of the compression latch, from polished to chrome-plated.

In the marine industry, flush-mounted chrome compression latches complement the design style with a clean, polished, protrusion-free look and sturdy lift-and-turn operation. For off-highway industry applications, such as excavators or backhoes, latches that employ a common tool and are painted black may be better suitable for a construction setting.


When choosing compression latches, make sure it’s from a reputable provider that can work with an OEM to discover their specific needs. Since these items are specific and often require customization, the provider must work efficiently to enhance the application’s efficiency and reduce its liabilities.

A good supplier will exceed safety and reliability criteria. The longer a provider has made compression locks, the better they will understand application needs and deliver the best goods and support. Engineers should find a supplier who can deliver the product’s stated function, durability, and customer service.
