This B-Line product is designed to maintain the spacing of rigid conduit during a concrete deck pour and prevent debris from falling into the conduit. It takes the place of pipe caps and tape and does for the 1/2" through 1" rigid what Spacers do for larger conduit. Although two products are sold: Quick Caps and Spacers, the Quick Cap does both while the spacer only maintains conduit distance.

These splices fall into a category called Insulation Displacement Connectors are used exclusively for plain old telephone wires (POTS), alarm and other low voltage circuits. You insert the wires, compress with a linesman pliers (or special tool) and the metal teeth inside will pierce the insulation and make a permanent connection that is moisture resistant. While the Dolphin is re-distributed by a variety of manufacturers and refers to the round tubular unit, the 3M UR performs a similar job but has a gel to protect the wires.
