Bell Wire Assembly, 2 Conductor, 41B4494-1, Compatible with LiftMaster, Chamberlain, Craftsman Operators, 25' Conductor Bell Wire, Microphone Wire, 1/4"" x 100 Ft Black, White

This wire is great for wiring up a new opener button. It's two conductor, white insulation there one side has a red stripe, identical to the wire that comes with most openers.Solid core keeps wire rigid, makes installation easier. Strips easily, but is still durable.

I ordered this wire expecting it to match the existing bell wire used for connecting to the garage door opening button. But I found that this wire is more flexible and has a stranded conductor instead of solid single conductor. This makes it easier to bend and work with.Highly recommend. All copper wire and polarity marked with red stripe.
