Empire 137B1200 Round U-bolt 12 Inch Pipe Steel

Product Description

The EMPIRE 137B1200 is a round U-bolt designed to secure 12-inch pipe in mechanical, plumbing, and HVAC piping systems. It features a 7/8-9 UNC thread size with a 4.25-inch thread length and an overall length of 13.75 inches. The U-bolt has a width of 9.625 inches to fit around standard 12-inch pipe. Constructed from uncoated steel, the 137B1200 meets fastener standards A-A-1192 A Type 24, MSS-SP-58, SP-69 Type 24, and WW-H-171-E Type 24. Four hex nuts are included. The unit weighs 6.43 pounds and ships as a single piece. Licensed pipefitters, plumbers, and mechanical contractors typically specify this hardware for pipe support applications.

This U-bolt is intended for use in commercial and industrial piping installations where large-diameter pipe must be clamped and supported. It suits 12-inch pipe runs in HVAC, process piping, and plumbing systems. The without-mount-plate configuration allows direct attachment to hanger rods or structural members. The high load capacity makes it suitable for heavier pipe sections carrying water, refrigerant, or gas in building mechanical rooms and utility corridors.
