UL Listed Riser Clamp - Heavy-Duty Vertical Pipe Support from China Suppliers and Factory for Fire Protection and Plumbing
UL US Listed & Code Compliant
Certified to meet UL 203 and MSS SP-58 standards, ensuring full compliance with NFPA 13, IPC, and local building codes for fire sprinkler and plumbing systems.
Robust Galvanized Carbon Steel
Made of high-strength carbon steel with electro-galvanized or hot-dip galvanized finish, offering excellent corrosion resistance for indoor and outdoor installations.
Dual-Bolt Design for Secure Grip
Two bolts evenly distribute clamping force, preventing pipe slippage even under full static load. The split design allows easy installation without disassembling the pipe.
High Load-Bearing Capacity
Engineered to support the full weight of vertical pipe runs, eliminating the need for additional hangers at every floor level and reducing overall installation costs.
Wide Compatibility
Fits standard steel, cast iron, and copper pipes (bare or insulated) in sizes from ½” to 8”, making it ideal for fire sprinkler risers, HVAC condensate lines, and plumbing stacks.
Simple, Fast Installation
Installs directly on the pipe and transfers the load to structural supports or floor openings, streamlining multi-story piping installations.

What is the primary function of a riser clamp?
A riser clamp is designed to support and anchor vertical pipe runs (risers). It clamps tightly around the pipe and transfers the weight load directly to the building structure or floor penetrations, preventing vertical slippage.
Are these riser clamps compliant with building codes?
Yes, our riser clamps are UL & cUL Listed and fully comply with UL 203 and MSS SP-58 standards. They meet the requirements for NFPA 13, IPC, and local fire protection and plumbing codes.
What materials and finishes are available?
Our standard riser clamps are manufactured from high-strength carbon steel. They feature an electro-galvanized finish for standard indoor protection, with hot-dip galvanized finishes available for enhanced corrosion resistance in outdoor or harsh environments.
Can these clamps be used on copper or insulated pipes?
Yes. They are compatible with standard steel, cast iron, and copper pipes (both bare and insulated) ranging from sizes ½” to 8”. Ensure you select the correct clamp size matching the outside diameter of the pipe or insulation.
Do you offer custom sizes or custom engineering?
Absolutely. While we stock standard sizes from ½” to 8”, we also provide custom engineering support to manufacture riser clamps for special load capacities, specific materials, or unique size requirements.
