Developed by ADC and Whirlwind, the 58-channel MASS Punch has terminated thousands of MASS connectors with a solid gas-tight connection system that accommodates 22, 24, or 26 ga. solid or stranded wire and permits easy rerouting of wires in the field. The multiple mounting hole sets permit easy mounting on standard hole centers and included tie wraps can be used to dress incoming wires. The panel works with our QB-2 spring-loaded or QB-115 manual punchdown tool.
