Punch Down Blocks

Stewart Connector’s series of SS-51 Punch Down Blocks help simplify field termination of AWG 22-26 solid copper wire cables. Optimized for Category 6a environments, the SS-51 Series features a unique notched head design that holds the wire securely in place prior to termination. The SS-51 series can be employed for wire termination in both patch panels and wall outlets using industry standard termination tools. Available in 1, 2, and 4 pair configurations, the SS-51 are available pre-printed with TIA 568A/B color coding. The unique design of the SS-51 Series Punch Down Block allows for staggered pair to pair arrangements in multi-port applications reducing alien cross talk in CAT6a applications.
