Overview

The nVent HOFFMAN AL3CRBLK is a field-installable 3-point latch kit designed for one-door Type 12 enclosures. This non-locking, clockwise (CW) operated kit is constructed from durable black steel, offering corrosion resistance and a professional appearance. It is specifically designed for enclosures with heights ranging from 36 to 48 inches. The AL3CRBLK ensures a secure seal against dust, dirt, and non-corrosive liquids, meeting NEMA 12 standards. Key features include adjustable latch rods that allow for precise gasket compression by relocating pins in the rod guides, simplifying maintenance and ensuring a consistent seal. The latch rods are equipped with rollers at the ends to reduce friction, facilitating smoother and more efficient door closure. This kit is compatible with most standard one-door Type 12 enclosures but is not suitable for Hoffman disconnect, CONCEPT, or PROLINE enclosures. All door openings are gasketed for a complete seal. The AL3CRBLK is an ideal solution for applications requiring frequent access where security is not the primary concern, such as control panels and electrical enclosures. SKU: AL3CRBLK. Manufacturer: nVent.

How to Install the AL3CRBLK Latch Kit

Instructions for installing the single-point or three-point latch kit on an enclosure door.

Estimated time: 30m

Tools needed:

Drill, Measuring tape, Screwdriver, Pliers

Supplies needed:

Latch kit components, Nylon washers, Handle gasket, Retaining ring, Spacers

  1. Prepare the enclosure door

    For single-point latch kits, locate and drill holes for the handle as shown in the diagram. For three-point latch kits, locate and drill holes in the door from the outside edges using the provided dimensions. Do not drill holes for rod guides.

  2. Assemble the latch mechanism

    Assemble the latch kit components as shown in the diagram. Install nylon washers and the handle gasket on the outside of the door to ensure proper sealing. If installing a three-point latch kit, and the latch rods are too long, select the correct hole and cut the rods approximately 3/8 inch from the center of the hole. Ensure you have selected the correct hole before cutting.

  3. Install the roller pin and adjust gasket compression

    Place the roller pin in the designated hole and secure it with the retaining ring. If the gasket compression is too great, move the roller pin one hole at a time until proper gasket compression is achieved.

  4. Position the latch using spacers

    Use the provided spacers to adjust the position of the latch, spacing it in or out as required for proper alignment and function.

  5. Verify clearances and safety

    Before energizing any circuits, verify that all internal and external electrical and mechanical clearances are checked to ensure that all assembled equipment functions safely and properly. This is critical to avoid electric shock.
