Why installers choose Fendix
A slimline fire collar for standard installs and difficult penetrations.
- Install over an existing cast-in collar or a standard core hole.
- Fit the open U-shape from one accessible side, without needing the collar to fully encircle the pipe.
- Designed for tight-clearance installations, including pipes positioned as close as 15 mm to a beam.
- Compliant for sockets, elbows, S-bends, four-way risers and other PVC-U DWV fittings.
- Avoid fire-rated bulkheads and box-outs in tested configurations.
- Fits where pipes elbow straight out of the penetration and run close to the underside of the slab.
Always refer to Assessment RTL FA 2981.03 for complete tested configurations and installation requirements.
