Voice and Data Wiring Blocks
Grainger carries wiring block options, including the 110 block type. Wiring blocks are electrical connections often used in telephone and data systems. The solid copper wires are punched down into open-ended slots that slice through the wiring insulation and hold the wire in position and make the electrical contact. This selection also includes split M and split B 66 block types. Shop Grainger for durable wiring block options, including 110 block, today.Close
