HOFFMAN AL7A T-Handle Latch Kit Steel NEMA 1

HOFFMAN AL7A T-Handle Latch Kit

The HOFFMAN AL7A is a steel T-handle latch kit designed to replace the standard slotted latch on NEMA 1 enclosures and hinged-cover pull boxes. It includes a keyed cylinder lock and all necessary mounting hardware for a complete installation. This kit is intended for maintenance personnel and installers who need to upgrade enclosure security with a lockable handle. The plated steel construction provides durability for indoor electrical applications.

Verify NEMA 1 enclosure compatibility before

Confirm that the target enclosure is rated NEMA Type 1 and uses a standard slotted latch that can be removed for this retrofit. The kit is specifically designed for Type 1 enclosures and hinged-cover pull boxes; it will not fit other NEMA ratings or latch styles. Check the existing cutout and mounting hole pattern to ensure the T-handle and cylinder lock will align correctly. No modifications to the enclosure body should be required if the original latch matches the standard design.

Integrates with existing enclosure hardware

The latch kit mounts directly into the existing latch opening using the included hardware, leaving the enclosure structure unaltered. It frees up the need for separate padlocks or external hasps by providing an integrated keyed locking mechanism. The T-handle allows for easy gripping and turning to engage or disengage the latching rod. This solution maintains the enclosure's original NEMA 1 rating while adding controlled access for authorised personnel only.
