Beware of the erroneous Grook template!
The utility holder seems like a fine device, but the markings on the template on the back of cardboard mounting did not match the device. I think this is inexcusably negligent of the company. Unfortunately, I did not discover this until I had already drilled holes in the wallboard and inserted the plastic sleeves. Had to pull 2 of them and drill 2 new holes. Bottom line: Before using the template, check to be sure it matches the holes on the device. If it does not, mark the drilling spots using the device itself rather than the template!
