China UL Listed Riser Clamp Suppliers - Factory Direct Heavy-Duty Vertical Pipe Support for Fire Protection and Plumbing
Key Features & Benefits
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 Construction
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.

Why Choose Our Riser Clamps?
Frequently Asked Questions (FAQ)
Our riser clamps are certified under UL 203 and MSS SP-58 standards, and are fully compliant with NFPA 13, International Plumbing Code (IPC), as well as local jurisdictional building codes for fire protection and plumbing systems.
They support standard bare or insulated steel, cast iron, and copper pipes ranging from ½” to 8”. Custom sizes and configurations can also be custom engineered for non-standard pipe diameters.
The clamps are manufactured from high-strength carbon steel. Electro-galvanized finish is supplied as standard, with hot-dip galvanized finishes available for enhanced corrosion resistance in aggressive or outdoor environments.
The dual-bolt split configuration allows the clamp to be placed around existing or installed vertical pipes without disassembling the pipeline, while the two bolts provide symmetrical clamping force to prevent slippage under full static weight.
Standard sizes (½” to 8”) typically ship within 5 to 7 business days. Custom engineered orders or oversized clamp configurations follow customized production schedules with global freight options.
Yes, they are specifically engineered to transfer vertical pipe loads directly to floor openings or structural floor framing, effectively stabilizing multi-story vertical pipe risers and reducing the need for intermediate floor hangers.
