Open splices are a common, but dangerous, electrical wiring issue. They need to be repaired right away but with traditional junction boxes you can easily find yourself wasting time and money rewiring and remaking open splices. Wire splices left open need a wire cover, and none are as easy-to-use as this. Cut how much time you spend in damp crawl spaces and hot, dark attics trying to work in poorly designed standard junction boxes. Go from dangerous, illegal open splices done by amateur handymen to a fully installed and safe junction box with just 4 screws and a few minutes of your time. This ingenious electrical wire cover makes the routine job of repairing open wire splices less tedious. If the connectors are tight and undamaged, you can bring electrical work up to code without splicing wires from scratch with the Open Splice Junction Box. Review: Great Junction Box - Excellent junction box that makes exposed connections a lot safer in an old house without having to undo wiring. Also helps when you have to repair wiring and want to add a junction box. Review: Great box, quick and easy install - I discovered unboxed splice wire in the basement. Didn’t want to unscrew the wire nuts and rethread everything into a box. This just made the job so much easier.
