Standard U-bolt from TPMC is a U-shaped rod with threaded ends, typically supplied with 4 hex nuts to form a complete clamping assembly. It is designed for heavy-duty applications, firmly securing pipes to supporting structure like I-beam, channel, or trapeze assembly to provide reliable support, anchoring, and guidance for piping systems.
