Installation Notes

U-bolts of this type are typically installed by plumbers, pipefitters, or general tradespeople. Before installation, ensure the mounting surface and any associated system are depressurized or de-energized as applicable to the application. Thread the hex nuts evenly on both legs to apply uniform clamping force, and avoid overtightening, which can deform the saddle or damage the clamped surface. Consult applicable codes such as IPC for pipe support spacing requirements in plumbing installations.
