Thomas & Betts 677 Erickson Coupling, 1" Trade Size
The Thomas & Betts 677 Erickson Coupling is a 1" trade size conduit fitting designed to join two runs of conduit end-to-end without requiring either section of conduit to be rotated during installation. Known industry-wide as an Erickson-style coupling, this fitting uses a draw-together design so electricians can complete a run even when one or both conduit lengths are fixed in place and cannot be turned. As part of the Thomas & Betts family of conduit fittings, the 677 coupling gives contractors a practical, no-turn connection method for standard 1" conduit systems. This 677 model gives contractors and electricians alike a straightforward option for completing 1" conduit runs without extra hardware or complex installation steps.
