Review on 🔌 Madison Electric Products MSB4G Adjustable: Painless Precision for Electrical Installations by Talapon Blackburn

I bought this because the Smart Switches needed more volume than a standard junction box to accommodate the Smart Switches. It turned out that the screw mounted on one end to hold the box in place was interfering with the smart switch on that end (the smart switch didn't fit in that position). I ended up having to buy a different type of junction box. The box itself is solid and the depth adjustment feature works well. You can easily use it in a touch up (old design) situation. I wish there were screw tabs on the other end of the box to make the mount more stable.
