Featuring an expandable spring for reuse and a compact shell for tight spaces, it replaces multiple traditional connectors, streamlining inventory and boosting efficiency across industrial, residential, automotive, marine, and appliance wiring tasks. ## Description The improved 3M O/B+ connector will help electricians do more with less. The O/B+ 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 percent 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.
