Suitable for many types of work - from industrial and residential construction, to automotive, Marine and appliance applications


3M™ Performance Plus™ Premium spring wiring caps are designed to connect and insulate copper wire in a variety of industrial applications. Quick bite springs create safe and reliable connections and ample room for expansion.




The modified 3M™ O/B+ spring wiring cap can help electricians with less effort. The O/B+ connector has a very small case, and the line specification has been increased. The improved spring can easily and quickly clamp wires and can hold two #22 AWG wires or three #12 AWG wires or four #14 AWG wires. The extremely small casing fits easily into tight Spaces, while the flexible lining protects workers from leaking wires. As the wire range expands, you can save money by buying fewer connectors.


O/B + replaces orange, blue and gray spring connectors, as well as 70% yellow spring connectors and wing connectors. This makes it easy to select the right connector for different wiring jobs. It also reduces inventory management, making it easy to find the right connector for each job.
