Overview

The nVent HOFFMAN AL2BRBLK is a black steel 3-point latch kit designed for field installation on one-door Type 12 enclosures. This kit features a keylock handle that operates with a 90-degree quarter-turn for secure access. It is engineered to provide a watertight and dust-tight seal, crucial for protecting sensitive electrical components. The adjustable latch rods, with relocatable pins in rod guides, allow for precise gasket compression adjustment, accommodating enclosure heights from 16 to 30 inches. Latch rod ends are equipped with rollers to facilitate smoother door operation, and all door openings are gasketed for a complete seal. The AL2BRBLK is constructed from durable black steel for corrosion resistance. It requires a square or triangular key for tamper resistance. This latch kit is compatible with standard one-door Type 12 enclosures but is not suitable for HOFFMAN disconnect, CONCEPT, or PROLINE enclosures. Installation involves punching or drilling a hole in the door for each latch, with complete instructions provided. nVent, a leader in electrical protection, ensures the reliability and performance of this latch kit, making it suitable for industrial applications requiring NEMA 12 protection against dust and moisture.
  • Each kit includes a handle, latch, latch rods, adjustable rod guides and all hardware
  • These kits are available with a key locking handle, a non-locking handle or a padlocking handle
  • Two keys are furnished with keylocking handles
  • Durable black steel construction for corrosion resistance

How to Install the AL2BRBLK Padlocking Handle Kit

Instructions for installing a single-point or three-point padlocking handle kit on an enclosure door.

Estimated time: 30m

Tools needed:

Drill, Measuring tape, Screwdriver, Pliers, Wire cutters

Supplies needed:

Padlocking handle kit components (latch rods, handle, gasket, screws, nuts, washers, spacers, etc.), Retaining rings, Roller pins

  1. Prepare the enclosure door

    WARNING: To avoid electric shock, do not energize any circuits before all internal and external electrical and mechanical clearances are checked to assure that all assembled equipment functions safely and properly. Locate and drill holes in the enclosure door according to the dimensions provided in the documentation. For three-point kits, drill from the outside edges. Do not drill holes for the rod guides.

  2. Assemble handle components and select rotation stop

    Select the appropriate latch rod stop for the desired handle rotation (clockwise or counter-clockwise). Assemble the handle parts and the selected latch rod stop as shown in the diagrams.

  3. Install the handle gasket and latch rods

    Install the handle gasket on the outside of the door to ensure proper sealing. If the latch rods are too long for your enclosure, select the proper hole and cut the latch rods approximately 3/8 inch from the center of the desired hole. Be certain of the hole selection before cutting.

  4. Install roller pins and adjust latch position

    Place the roller pin in the designated hole and secure it with the retaining ring. If gasket compression is too great, move the roller one hole at a time until proper gasket compression is achieved. Position the spacers for the correct location of the latch. Use the provided washers to adjust the position of the latch in or out as required.

  5. Final Assembly

    Complete the assembly of the handle kit by securing all components with the provided screws, nuts, and locknuts as indicated in the diagrams.
