Single clamp F 28mm. Quantity per package: 100 pieces. 928F

What is it and what is it used for

The single clamp F 28 mm is a metal component designed for the stable routing of fire-resistant cables and other conductors in building installations. Thanks to its double profiling, it offers increased rigidity while maintaining compact dimensions, facilitating its concealment within various partitions – from PVC pipes to steel conduits.

Key features and benefits

• Double profile – enhanced resistance to bending ensures the clamp does not deform under load, extending the service life of the entire cable route.
• Easy installation – a 6.5 mm hole enables quick mounting using standard DA anchors and BTS concrete screws; alternatively, an MSD plug with a TG screw can be used.
• CNBOP certificate – confirms compliance with Polish fire safety standards, which is crucial for both installers and building owners.
• Versatility – suitable for use with PVC pipes, multi-layer pipes, steel conduits, and copper installations.
• High material strength – made from hardened steel, ensuring resistance to corrosion and mechanical damage in challenging conditions (concrete, solid brick, sand-lime block, natural stone).

Installation and compliance with standards

• Procedure: drill a 6 mm diameter hole in the substrate (concrete, brick), insert a DA anchor or MSD plug, then secure the clamp with a BTS screw or TG screw – the entire process takes only a few minutes.
• Compliance: the product holds CNBOP approval and meets requirements for fire installations in Poland; it can be used without additional certifications in projects complying with PN‑EN 13501‑2 standards.
• Practical tips: when installing in brittle materials (e.g., natural stone), it is recommended to use an MSD plug with a TG screw for better adhesion; in concrete, BTS screws are most effective due to their high tensile strength.

The single clamp F 28 mm combines installation simplicity with robust construction – an ideal choice for both professional installers and investors prioritizing fire safety in their facilities.
