Jumbo Mfg 2950 Soil Pipe Clamp 4 Inch

Product Description

The JUMBO MFG 2950 is a soil pipe clamp designed to mount to the side of a soil pipe spigot. It provides a secure attachment point for supporting or anchoring drain, waste, and vent piping in plumbing systems. The 2950 fits 4-inch pipe and is compatible with both standard-weight and extra-heavy pipe, giving installers flexibility across common pipe classes. Plumbers and pipefitters install this clamp during rough-in work to maintain proper pipe alignment and support spacing as required by the applicable plumbing code.

This clamp is suited for residential and light commercial plumbing installations where cast iron soil pipe is used for drain, waste, and vent systems. It attaches to the spigot end of the pipe, making it useful in tight spaces or situations where a riser clamp or band hanger is not practical. Its compatibility with both standard and extra-heavy pipe makes it a versatile support option across different pipe schedules commonly found in retrofit and new construction work.

Installation Notes

Installation is performed by licensed plumbers in accordance with the International Plumbing Code (IPC) and local authority requirements for pipe support spacing. Shut off flow and depressurize the line before servicing any connected piping. Ensure the clamp is fully seated on the spigot before tightening fasteners. Do not over-tighten, as this may distort the pipe or clamp seating surface.
