Installation Notes

Installation is typically performed by plumbers, mechanics, or general tradespeople using standard wrenches or sockets. Ensure the mounting surface and pipe or member being secured are clean and properly aligned before tightening the hex nuts. Do not overtighten, as excessive torque can deform the pipe or crack brittle substrate materials. Follow applicable local mechanical or plumbing codes when using in a regulated piping system.
