Installation Notes

U-bolts of this type are typically installed by plumbers, pipefitters, or general contractors using standard hand tools and wrenches. Shut off fluid flow and depressurize any pipe run before removing or repositioning existing fasteners. Confirm that the U-bolt inside width clears the pipe outside diameter before tightening the plate nuts evenly to avoid cocking the assembly. Follow applicable local mechanical or plumbing codes when installing pipe hangers in permanent structural applications.
