Overview

The SRB Storm PVC Finishing Collar 90/100mm with grate is the fitting that finishes a stormwater outlet flush with a paved or landscaped surface. It accepts the pipe, carries the outlet through the surface, and the integral grate keeps leaves and debris out while letting the water flow. It is the tidy end point for a patio inlet, driveway outlet or tank overflow.

It is designed for 90mm pipe and is available in this 90/100mm variant to bridge the two common stormwater pipe sizes. It is made from UV-stable PVC or ABS, fits with a solvent weld connection, and complies with AS/NZS 1254 for stormwater fittings.

Frequently Asked Questions

What is a finishing collar used for?

It finishes the point where a stormwater pipe meets a paved or landscaped surface. The collar carries the pipe outlet through the surface, and the integral grate keeps debris out while letting water drain. It gives a clean, flush finish instead of an open pipe end.

Does this collar fit 90mm or 100mm pipe?

It fits both. The collar is designed for 90mm pipe, and this 90/100mm variant bridges the two common stormwater sizes. Confirm your pipe size before ordering and solvent weld the connection for a watertight joint.

Can I use it for a rainwater tank overflow?

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

Is it suitable for driveways and paths?

Yes. The low-profile collar sits flush with the finished surface, which makes it suitable for patios, driveways, paths and landscaped areas where a neat, trip-free stormwater inlet is needed.
