The REC-BCN658 is an open jaw version of the REC-658U latched-type tool. The open jaw can easily fit into tight situations where the closing of a jaw latch would be a problem. The jaw is covered with a rubber boot designed to provide some insulated protection against “brush” contact with energized cables. The tool should not be used as an insulated tool since the dies and die holding pins are always exposed.; The head can be turned 180° and positioned to accommodate the operator’s work methods. A complete cycled compression is accomplished by the simple squeeze of a trigger. A factory preset by-pass cartridge assures a complete compression every time. Its 6-ton output is equal to any comparable handheld, hydraulic compression tool and far exceeds any mechanical crimper. The REC-BCN658 is supplied with D3 nest dies, which can be interchanged with Kearney, or T&B “O” type dies. If you wish to use the Huskie or another brand of “W” type dies, simply slide them over the D3 nest dies and snap in position. The output pressure, of the REC-BCN658 can be checked with the PG-15 pressure gauge when necessary.
