The THOMAS BETTS C109 1 1/4 EG is a galvanized steel pipe and conduit clamp sized for 1.25-inch pipe or conduit. Constructed from 14-gauge steel with a silver galvanized finish, this clamp is rated for a load capacity of 600 pounds. It is used to secure conduit or pipe to structural surfaces in electrical, mechanical, and plumbing installations. Licensed electricians, pipefitters, and mechanical contractors install this type of clamp during rough-in work to maintain proper support spacing per applicable code requirements.
This clamp is suited for commercial and residential applications where rigid or intermediate metal conduit, EMT, or standard pipe runs require secure mechanical support. The galvanized finish provides corrosion resistance in indoor and moderately exposed environments. Its 600-pound load rating makes it appropriate for single-pipe or conduit support points along runs where consistent, code-compliant spacing is required.
Designed as an OEM-style replacement or standard-fit clamp for 1.25-inch pipe and conduit support applications across all conduit types in electrical and mechanical installations.
Installation is typically performed by licensed electricians or pipefitters following NEC or IPC support spacing requirements for the conduit or pipe type being secured. De-energize all circuits and relieve system pressure before working on existing runs. Use appropriate fasteners rated for the mounting surface to ensure the full 600-pound load rating is maintained. Do not exceed the rated load capacity of the clamp.
