Single Bossed Clamps – Without Lining (VdS/FM Approved, Galvanised) 109716

Fire-Protection Certified • High Load Capacity • VdS/FM Approved

Single Bossed Clamps – Without Lining (VdS/FM Approved, Galvanised) 109716 are high-strength, corrosion-resistant galvanised pipe clamps engineered for certified sprinkler and fire protection systems. Designed and approved in compliance with VdS and FM standards, these clamps deliver secure, long-term performance in industrial, commercial, and residential installations.

Constructed from hot-dip galvanised steel, the clamp provides robust support and corrosion resistance even under high load conditions. The practical combination cross-head bolts and captive washers ensure fast, tool-friendly assembly, while the wide range of connection threads (M8–M16) offers flexibility for multiple mounting systems. Optimised for sprinkler pipe installations, the clamp ensures safe, reliable, and certified mechanical performance in fire safety environments.
