Compression Latches & Locks

 (11 product groups)

What are compression locks and latches?

Compression latches, also referred to as compression cam latches, utilize gaskets pressed against a door or panel opening to create a secure seal, effectively keeping out dust and moisture. Widely employed in industrial cabinets, panels, and various enclosures, these latches serve the fundamental purpose of securely closing doors.

These fasteners hold two surfaces together with a gasket, featuring a trigger release mechanism for opening. Similar to standard cam latches, compression latches consist of a base and a cam lever, turned to lock the latch. Additionally, a compression lock, a variant of the compression latch, integrates keys and a locking mechanism for enhanced security. Each compression lock from our collection is supplied with two sets of keys.

Compression latches can either be fixed, providing a set compression level, or adjustable, allowing for a change in compression with a wide grip range. Notably, their tight seal makes them well-suited for environments with vibrations, such as industrial machinery, contributing to noise reduction. Furthermore, they prove effective in sealing against dust or moisture, while their ease of installation adds to their practicality.

What are the benefits of using compression latches and locks?

The primary advantage of employing compression locks lies in their effective safeguarding when combined with gaskets on the application.   This makes compression latches an optimal choice for access hardware in various applications, including:

  • Electrical enclosures
  • Telecom equipment lockers
  • HVAC system access panels
  • Industrial generators
  • Marine vehicles
  • Aerospace machinery
  • Medical enclosures
  • Automotive vehicles


These systems are routinely exposed to diverse environmental elements, and by utilizing compression latches, the risk of rain or debris infiltration, potentially causing harm to the internal electrical components, is mitigated.

Furthermore, the use of compression latches in the mentioned applications offers an additional advantage: resistance to vibration. This is particularly crucial in scenarios where vibrations may arise from factors such as running engines or uneven terrain. The tight seal formed by the gasket ensures that access panel doors remain secure, preventing any rattling or unintended unlatching during periods of system vibration.
