The New Macey 150 Amp Quick Release Back-to-Back Receptacle is engineered for high-current underground mining applications where coupling speed, operator safety and long-term durability are critical.

Unlike traditional back-to-back systems that rely solely on manual force through dual jacking screws, this unit incorporates a heavy-duty rack and pinion mechanism to provide controlled mechanical advantage. The result is faster coupling, smoother engagement and significantly reduced physical strain during repetitive cable moves.

This is a genuine mechanical innovation in high-current cable management — purpose-built to reduce operator fatigue, improve safety outcomes and increase productivity underground.

Constructed entirely from stainless steel 304 and designed for harsh, dirty and moisture-prone environments, the assembly delivers exceptional structural strength while remaining serviceable through its bolted body construction.
