Front style terminal blocks permit wire entry cavity on same plane

TYCO ELECTRONICS Eurostyle terminal blocks include front style plugs that provide a wire entry cavity and activating screw head located on the same plane — parallel to the direction of the plug. Plugs are densely stacked, side by side, while facilitating easier termination and removal of wires without the need to unplug the connector. Front style plugs include captive screws to prevent the screws from backing out.
