A compression handle latch works in a way to ensure tight closure through a handle mechanism that compresses a seal on a door, panel, or compartment. It works in the form of a pulling handle applying pressure in such a way that the door or panel forms a tight seal against its frame. This prevents moisture, dust, and other elements from entering, and hence is of great value in an environment like marine, automotive, and recreational vehicles. For instance, the TopSeek compression handle latch is able to offer a compression of up to 5mm for exact fit upon shifting door alignment due to environmental conditions.
The practical use of a compression handle latch involves using a spring-loaded or mechanical system to pull the locking mechanism tight as one turns or pulls the handle. NMMA estimates that these products, such as compression handle latches, are able to provide 30% more efficiency in sealing when compared to traditional latches that depend on simple mechanical locking without the additional force of compression. This added compression ensures the latch holds tightly, even when exposed to wind or vibrations. For example, owners of recreational vehicles say that compression handle latches cut the costs of maintenance by 25% as compared to other, non-compression-based, older models of door closings.
A perfect example would be the boating industry where producers have been nudged to make use of compression handle latches because customers insisted on getting watertight closures which are much secure. The “SeaGuard” marine latch has been one of the popular alternatives that have grown to become somewhat of an industry standard, with over 40% of new boats in various designs now incorporating compression latches. This transition was informed by feedback that traditional latches often failed to provide a tight seal in rough conditions, leading to water damage.
According to John Matthews, CEO of TopSeek, “The adaptability of the compression handle latch to varying conditions and to provide a secure seal in different environments makes it an ideal option for those who aim for reliability and performance in the long run.” This pretty much describes the general role of compression handle latch; that is, providing reliable performances while introducing a simple and effective locking system for a number of industries.
