Anvil 0500421102 Riser Clamp 4 in 300 lb 12.5 in

4-Inch Copper-Plated Riser Clamp

The Anvil 0500421102 riser clamp supports 4-inch copper tube with a 300 lb load capacity. Its carbon steel body uses a copper-plated finish for compatibility with copper piping systems. The clamp spans 12.5 inches overall with a 1-inch width and mounts via 0.5-inch diameter holes. This component suits plumbing installations requiring vertical pipe support.

Sustained Load and Temperature Performance

Rated for 300 lb at a maximum operating temperature of 450 Degrees F, the clamp maintains its grip under continuous thermal cycling. The carbon steel construction resists creep when hot water lines expand and contract repeatedly. No cushion material is present, so metal-to-tube contact transfers load directly without compressible layers that could relax over time. The design meets MSS SP-58 Type 8 requirements for hanger performance.

Replaces Uncushioned Steel Clamps on Copper Risers

This clamp upgrades plain steel riser clamps that lack a copper-plated finish, eliminating the galvanic corrosion risk when dissimilar metals contact copper tube. The jump is worth it on hot-water risers where temperatures approach the 450 Degrees F limit and sustained 300 lb loads are expected. It does not suit installations requiring a cushioned interface or insulated pipe support.
