Lithonia Lighting track end mount

Quick fix, designed for Lithonia Lighting tracks, but can be used with other similar "electric rails" (check sizes on the scheme above)

Might be useful if you are going to set heavy-weight light modules on the track mounted to the wall (in my case I found that common screws in the middle of the track are not enough).
