By positioning the UB2A on the conductor and pre-crimping, the conductor is prevented from slipping out of the connector before the crimp is completed. A thin membrane molded into the tap wire entry port also assists the craftsperson by securing the tap wire until the crimp is completed. Like the UR2, a factory-installed sealant insulates against corrosion, and seals out moisture. The UB2A-D, a dry version, is available as well. The UB2A permits tapping directly onto an existing conductor without interrupting service. In ready access closures, the UB2A eliminates cutting cable pairs, opening pairs, and piecing out wires. Fast and easy to work with the UB2A accepts 19-26 AWG (0.9 mm- 0.4 mm) plastic-, paper-, or pulp- insulated solid copper wire with a maximum O.D. of .082" (2.08 mm). The wires joined can be of different wire gauges. The UB2A and UB2a-D are available in box, bulk and bin.
