Great Buy!
Size: 6 Outlets, Style: Black
Great product. I installed it in built-in cabinets that were installed in my office. It comes with a template, so you don’t have to measure or guess.

Inaccurate Measurement
Size: 6 Outlets, Style: Black, Size: 6 Outlets, Style: Black
Dimensions are incredibly inaccurate. Picture illustrates that the bottom of the power strip should fit a 9.9" opening. Actual size is 12.5". I can't fit this into the pre-made opening on my desk. I will be returning it
