A compression latch works in such a way that a spring-loaded mechanism puts pressure on a door or hatch for its tight and secure seal. The turning or pulling of the latch will compress the spring inside it, which, in turn, allows the latch to engage and apply force against the door or cover. This compression makes a tight seal that does not allow water, dust, or air to come into the enclosure. Such types of latches normally find their applications in an environment that requires security and sealing, for example, in marine, automotive, and industrial use.
The ability of a compression latch may be measured from the consistency in force it offers. A usual type of compression latch provides pressure up to the range of 50 to 200 pounds with respect to the size and type of design applied. This pressure is enough to ensure that the door remains securely closed even in rough conditions. In a 2021 case study by the Industrial Equipment Journal, it was found that compression latches outperformed traditional latches in providing a water-tight seal by 30%, reducing the risk of corrosion and damage in high-moisture environments.
The design of a compression latch typically consists of a rotating handle or key that controls the spring mechanism. The latch can be fitted with a rubber gasket for added sealing qualities to ensure that no contaminants can enter the enclosure. In a report provided by the NMMA in 2020, it was determined that boats with compression latches showed 25% fewer water intrusion incidents than those with mechanical latches.
When it comes to choosing a compression latch, one of the main factors is its durability. For example, a high-quality stainless steel latch is resistant to corrosion and wear in harsh marine and industrial environments. A compression latch made from resistant materials can serve 10 years, while its low-quality version needs replacement every 3 to 5 years.
Compression latches can also be convenient. They usually provide for fast operation, which is necessary in applications that require easy access. For example, in the automotive industry, compression latches are applied in truck doors where the truckers need to have fast access to the cargo compartment. According to a 2019 survey by the Automotive Equipment Association, 40% of truck operators preferred compression latch for this reason.
Compression latches can provide the ruggedness and security needed in harsh environments for those looking to secure their enclosures with a quality solution.
