Metal plug for G-K 4mm for panels 32–38mm 9438HRM

What is this anchor for?

The HRM metal anchor is a fastening element designed for use in hollow cavities — it performs ideally when mounting on gypsum board, particleboard, or plywood, as well as on suspended ceilings. It works by expanding its rear arms upon insertion, creating stable resistance across the entire inner surface of the panel. This not only increases load capacity but also eliminates the risk of pull-out under static and dynamic loads.

Sample applications: towel bars, wall shelves, cabinets, curtain rods, lamps, and elements mounted on cavity walls or hollow brick.

How to install it?

Installation is simple, but selecting the right tool is critical. For single installations, a screwdriver or cordless drill is sufficient — simply press the anchor in and tighten the screw. However, for multiple fixings (e.g., installing an entire wall or ceiling), CELO MZA 100 installation pliers are essential. They enable precise, single-step, controlled insertion of the anchor without risk of damaging the panel or improper expansion.

No drilling is required — the anchor is drill-free, speeding up work and reducing dust.

Safety and compliance

Made of metal — therefore not flammable and compliant with Class A1 according to DIN 4102. Possesses CNBOP approval, confirming compliance with Polish building requirements for fasteners in drywall constructions.

Works safely in panels from 3 mm to 45 mm thick — this specific model (9438HRM) is optimally suited for 32–38 mm thickness, typical for standard G-K boards.
