ARLINGTONINDUSTRIES NM96 627001 Non-Metallic Push-in Connector, Black Button, 1" (Pack of 25)

I have to say that in comparison to another manufacture, who makes a similar to looking connector, but it's gray in color that there is really nothing to compare.... Arlington's connector is flexible and pliable the other brand X.... breaks easily and is very difficult to push 2 cables throughGo Arlington !!!
