Overview

The SRB Storm PVC Finishing Collar 90mm with grate finishes a 90mm stormwater outlet flush with a paved or landscaped surface. It carries the pipe through the surface, and the integral grate keeps leaves and small debris out of the drain while the water flows through. It is the neat end point for a patio inlet, a driveway outlet or a tank overflow.

It is made from UV-stable PVC or ABS, fits with a solvent weld connection, and complies with AS/NZS 1254 for stormwater fittings. This is the 90mm version of the collar range, with a 90/100mm variant also available for bridging pipe sizes.

Frequently Asked Questions

How is this different from the 90/100mm collar?

This collar fits 90mm pipe only, while the 90/100mm variant also accepts 100mm pipe to bridge the two common stormwater sizes. If your pipe is 90mm, either collar works; if you are joining to 100mm pipe, use the 90/100mm version.

Can I use it as a surface inlet on a driveway?

Yes. The low-profile collar sits flush with the finished surface, which makes it suitable for driveways, patios and paths. The integral grate keeps debris out while letting surface water drain into the pipe below.

What does the grate do?

The grate filters leaves, grit and small debris so they do not wash into the pipe and cause a blockage. It is rigid and fixed, so there is nothing to lose, and the water flows through the openings into the drain.

Is it suitable for a tank overflow?

Yes. A finishing collar with a grate is a tidy way to finish a tank overflow outlet, directing the overflow water away from the tank while keeping the outlet looking neat and stopping debris from getting in.
