Thomas & Betts WT-157N Wire Terminal Crimping Tool

The Thomas & Betts WT-157N Wire Terminal Crimping Tool is a manual hand-operated crimping tool designed to produce secure, repeatable terminations on Sta-Kon insulated terminals, splices, and disconnects. It uses the patented Shure Stake® Positive Ratchet mechanism to ensure a complete crimp cycle before release, delivering consistent, high-quality terminations. Built on a heavy-duty steel frame with cushion/palm grip handles, the tool supports 22–10 AWG wire (application dependent) and is designed for UL-listed Sta-Kon termination systems. Part of the Thomas & Betts (ABB) Sta-Kon family, this tool is suited for electrical panel fabrication, industrial maintenance, OEM assembly, utilities, telecommunications, and commercial electrical installations. It is commonly used by maintenance electricians and contractors for new installations, retrofits, and replacement of older crimp tools, featuring precision crimp nests and controlled ratchet release for reliable mechanical and electrical connections while reducing operator fatigue. Common replacements include WT145A, WT145C, and ERG4001.
