There is no need to strip the quick wire branch connector, the main wire does not need to be stripped when using, and the handle is used for quick crimping when the branch is connected.
This push in connector is 1 in 2 out, which is different from 222 seriesconnector. It can be combined into 2 in 4 out, 3 in 6 out, 4 in 8 out and also 5 in 10 out etc. Easy to setup.
