IDEAL INDUSTRIES 30-707JC CAN-TWIST BLUE 1000PC

CAN-TWIST™ Wire connectors of ergonomic, easy-twist design - only a few turns are needed to achieve torque, without the need to pre-twist wire. Heat-set, square-cut springs stay in place and firmly grip wire for superior connectivity. Flexible outer shell virtually eliminates cracking, expanding to securely accommodate wire indicated by white expansion lines. Extended skirt length provides over-strip protection. Sleek design helps reduce box fill.
