Application brief 02
What if an elbow or nearby service leaves almost no room?
The 20 mm-thick body, open U-shape and 15 mm-wide arms allow Fendix to fix from the accessible side without needing to fully encircle the pipe.

The stack turns beneath the slab inside a confined zone. Fendix installs against the soffit from the accessible side of the penetration.
The U-shaped design protects the penetration without needing the collar body to fully encircle the pipe.
A sprinkler pipe runs immediately beside the stack penetration. The slimline Fendix body fits in the available space, where a conventional circular fire collar would contact the sprinkler pipe.
The 20 mm-thick body and 15 mm-wide extending arms reduce the space needed around the penetration.
The PVC pipe changes direction almost immediately below the slab, leaving no straight pipe length for a conventional circular collar to pass over.
The open side is positioned around the pipe and the collar fixes directly to the soffit from below.
Typical problem condition
Before any collar is fitted
The bend begins at the slab face. Without a suitable tested retrofit fire collar, this type of condition can require pipework alterations or the construction of a bulkhead.
Fendix approaches the penetration from the open side, so the existing elbow can remain in place.
Confirm the complete pipe, slab, fitting and FRL configuration against RTL FA 2981.02 before installation.

Yes, if the penetration is within the collar opening.
No. The open U-shaped form installs from the accessible side without needing the collar body to fully encircle the pipe.
Yes. Fendix can also be installed over standard PVC-U penetrations without sockets or nearby obstructions.
Have a tight penetration?
