Model: A-1442-146-30
Material: Zinc Alloy | Finish: Electroplated Chrome | Rating: IP40, UL FTTA2/FTTA8 Class 1
Product Description
The A-1442-146-30 is a compression door lock with lever and raised trigger mechanism, designed for enclosure doors and access panels where straightforward operation, clean aesthetics, and reliable closure are the primary requirements. If you’re specifying hardware for industrial cabinets, equipment housings, or control panels where a low-profile lever lock with exposed mounting suits the installation, this lock is a practical and well-proven choice.
The lock body is manufactured from zinc alloy with an electroplated chrome bright finish — a combination that resists corrosion and maintains its polished appearance over extended use. The chrome finish gives the hardware a clean, professional look that works well in both indoor industrial environments and commercial equipment applications where appearance matters alongside function.
The raised trigger head style is a defining feature of this lock. The trigger mechanism provides a distinct tactile release point — users press the raised trigger to disengage the latch and open the lever. This separation between release action and opening action reduces the likelihood of accidental opening, which is useful in applications where the enclosure is in a busy environment or where unintended access is a concern. The trigger profile is raised above the face surface, making it easy to locate by feel without visual confirmation — a practical detail in low-light or gloved-hand environments.
The lever operates as a separate handle mechanism with a built-in release function. A separate mounting touch mechanism is available in two configurations — embedded or rising — allowing flexibility in how the release action is integrated into the door design. This makes the A-1442-146-30 adaptable across different enclosure designs without requiring custom hardware modifications.
Exposed mounting is the installation method for this model. Unlike concealed mounting designs, exposed mounting is straightforward to install and service — the bracket and nut hardware is visible and accessible, making installation faster and allowing for simpler maintenance when the lock needs to be adjusted or replaced. For applications where hardware visibility is not a concern, exposed mounting is often the more practical choice.
Access restriction is button locking, meaning the door can be opened by pressing the trigger — no key required. This open-trigger design suits applications where controlled access is not required but reliable, repeatable closure is important. The lever provides a positive grip point for opening and closing, and the compression action pulls the door firmly into position on each closure cycle.
The lock is rated at IP40, providing protection against solid particle ingress in standard indoor environments. It’s suited for applications where dust and moisture ingress protection at IP65 level is not a requirement — indoor electrical panels, equipment cabinets, control enclosures, and similar installations where the environment is relatively controlled.
Performance is backed by documented specifications. The handle bearing tension value is rated at ≤ 500N, and the maximum static load rating is 200N — sufficient for typical cabinet and enclosure door applications across a light duty load range.
The A-1442-146-30 complies with UL FTTA2 / FTTA8 Class 1 standards, making it suitable for industrial and commercial applications where compliance documentation is part of the specification requirement.
