Model: A-1442-146-40
Material: Zinc Alloy | Finish: Powder Coating | Rating: IP40, UL FTTA2/FTTA8 Class 1
Product Description
The A-1442-146-40 is a compression door lock with lever and raised trigger mechanism, designed for enclosure doors and access panels where straightforward operation, durable construction, and reliable closure are the primary requirements. If you’re specifying hardware for industrial cabinets, equipment housings, or control panels where a lever lock with exposed mounting and a robust black finish suits the installation, this lock delivers dependable performance in a practical package.
The lock body is manufactured from zinc alloy with a powder coating finish in black — a combination that resists corrosion and impact while maintaining its appearance over extended use in demanding industrial environments. The powder coating provides superior resistance to scratches, abrasion, and incidental contact compared to chrome-plated finishes, making it the more practical choice for high-traffic applications or installations where the door or panel faces regular physical exposure. The black finish integrates cleanly with dark-colored enclosures and equipment panels, giving a consistent, professional appearance across the installation.
The raised trigger head style is the defining functional feature of this lock. The trigger mechanism provides a distinct, protruding release point — users press the raised trigger to disengage the latch before operating the lever. This two-step action separates the release from the opening movement, reducing the likelihood of accidental opening in busy environments or where unintended access is a concern. The raised profile makes the trigger easy to locate by feel, which is a practical detail when working in low-light conditions or with protective gloves.
The lever operates as a built-in handle with an integrated release function. A separate mounting touch mechanism is available in two configurations — embedded or rising — allowing flexibility in how the release action integrates into the door design. This adaptability makes the A-1442-146-40 suitable across different enclosure types and door panel designs without requiring custom hardware modifications.
Exposed mounting is the installation method for this model. Unlike concealed mounting designs, exposed mounting keeps the bracket and nut hardware visible and accessible, making installation straightforward 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 faster and more cost-effective installation approach.
Access restriction is button locking, meaning the door releases by pressing the trigger — no key required. This design suits applications where controlled key access is not necessary but reliable, repeatable closure is important. The compression action pulls the door firmly into position on each closure cycle, maintaining consistent contact between door and frame throughout the service life of the lock.
The lock is rated at IP40, providing protection against solid particle ingress in standard indoor environments. It’s suited for applications where a higher IP rating is not a specification requirement — indoor electrical panels, equipment cabinets, control enclosures, and similar installations where the environment is relatively controlled and moisture ingress protection is not critical.
Performance is backed by documented specifications. The handle bearing tension value is rated at ≤ 500N, and the maximum static load rating is 200N — appropriate for light duty cabinet and enclosure door applications. These parameters ensure consistent, reliable operation throughout the lock’s service life under normal use conditions.
The A-1442-146-40 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.
