Double DFT holder for 28mm socket 928DFT

Safe and rapid mounting of fire-resistant cables

The DFT clamp for a 28mm anchor is a solution specifically designed for fire-resistant installations, where stability and integrity of the cabling system are critical. Engineered to perform under fire conditions, it provides 90-minute fire resistance—confirmed by the R90 certification—ensuring cables do not prematurely collapse under high temperatures.

Installation in seconds, without additional tools

Using a gas-powered anchor tool, installation takes just a few seconds. The plastic component of the clamp is directly attached to the anchor’s stem—no screws, threads, or additional fastening elements are required. It is compatible with most anchors and nailers on the market, not just CELO products. This significantly speeds up the installer’s work, especially when dealing with large numbers of mounting points.

Stability and compliance with standards

The metal structure with reinforcing ribs ensures better cable grip and increased resistance to mechanical loads. The system meets the requirements of DIN 4102 for parallel installation of fire-resistant cables, and its ETA approval and CNBOP certification guarantee compliance with Polish and European fire protection regulations. For fire-resistant applications, mounting must be performed on solid, fire-resistant surfaces such as concrete or brick.

Why it works

The double structure allows for the simultaneous retention of two cables at a single point—without risk of movement or abrasion between them. This not only simplifies cable organization but also reduces the risk of insulation damage caused by material expansion under heat. Compared to single clamps, it provides greater control over cable layout in trays and conduits.
