I wanted to conceal my surge protector/power strip in my office, so I measured the power strip first to insure it would fit inside this box. I like that there is nearly a one inch opening on each end to allow for the cords - in my case I really needed it to accommodate the end of the surge protector. I also like the hole on the side as it gives you options to configure your specific cord needs. Although the cost seems a little high for a "plastic box", it keeps everything contained with a neat, orderly appearance, and keeps the cords away from my dog who likes to sleep under my desk. Since it should last for years, it was worth it to me. In fact, I bought a second one. I used this in conjunction with "Kootek 118 inch cable management cord cover sleeve" which is reversible to either black or white and keep my cords contained outside of this box.
