Application brief 04

Fire collars for
Smart Traps &
Smart Elbows.

A small fitting shouldn’t mean a bulky bulkhead.

Smart Traps and dry floor waste fittings can leave an awkward fire-stopping detail beneath the slab. Fendix fits around supported configurations, keeping the solution compact and the pipework in place.

Fitted around the Smart Trap.

Fendix fixes directly to the underside of the slab, around the existing fitting. The Smart Trap and pipework stay in place.

Not every collar fits
around this.

The Smart Elbow’s wider body can make a conventional circular collar difficult to fit, especially close to the slab.

For supported configurations, Fendix’s open U-shape fits around the fitting with a collar body just 20 mm deep. A slimline solution without reworking the pipework or adding a bulky enclosure.

Can Fendix suit my Smart Elbow?

Send us a photo of the fitting and the pipe size. We’ll help you match the installation to the supported configuration in RTL FA 2981.03.

The compliant solution

Before you build a bulkhead,
look at Fendix.

RTL FA 2981.03 includes supported PVC-U fitting and dry floor waste kit configurations. Where the installation matches the report, Fendix can provide the fire-stopping solution without the bulkhead or pipe alterations that may otherwise be needed.

Quick answers

Need to fire-stop a Smart Trap on your project?

Can Fendix be used with a dry floor waste kit?

Yes, for supported configurations. RTL FA 2981.03 includes dry floor waste kits and PVC-U fittings within its approved size and installation limits.

Does a Smart Trap always need a fire-rated bulkhead?

No. A bulkhead is not the only option. Where the configuration is covered, Fendix can fit directly around the fitting and provide the fire-stopping solution.

Can you check my Smart Trap or Smart Elbow?

Yes. Send Fendix a clear site photo and the pipe size. Add the required FRL if known, and we’ll help identify the applicable configuration.
