Product Overview

The improved 3M O/B plusConnector will help electricians do more with less. The O/B plus connector combines a very small shell with an increased wire range. The improved spring bites wire quickly with less effort and accommodates from two #22 AWG wires up to three #12 AWG wires or four #14 AWG wires. The very small shell fits easily into tight spaces and its flexible skirt helps protect workers from contact with over stripped wires. With such a wide wire range, you can save money by buying fewer connectors. O/B + replaces the orange, blue and gray spring connector style connectors, as well as 70% of the yellow spring connector and wing style connectors. This simplifies selection of the right connector for a wide range of wiring jobs. There's also less inventory to manage and a better chance you'll have the connector you need to do every job.
