Ease of Installation Is a Big Deal for Me
I always look for a box that is simple to install with standard tools. Features like adjustable clamps, pre-set screw holes, and easy-to-tighten wings make a difference. The easier it is to secure the box, the more confident I feel about the job.
Compatibility With My Electrical Devices
