The best thing about this particular Jbox is its exceptional durability. The design is what I've always been looking for as an electrician. The two screws fit perfectly on the inside of the jbox and drill right into the stud with ease. If you have read some of the reviews a gentleman was kind enough to provide me with the full dimensions of this particular jbox which was just what I needed to make my purchasing decision. The manufacturer must discontinue this type because its dimensions appear as if they were created in CAD. Overall a great Jbox for the experienced electrician and DIY enthusiast.
