About this item No Drilling & No Glue: Unlike under desk cable management trays that require drilling for installation, Ourhom's under desk cable trays require no drilling and no glue, making them truly non-destructive to your desk and allowing you to easily change their position as needed. Suitable for tables with a thickness of 0-1.7 in. Two-in-One & Retractable: It is a retractable cable management tray that connects two 16 in trays and expands to 31 in by stretching, allowing for more organization space. It has been tested to hold three 9.45*4.33 in power strips at the same time. Cables from Messy to Tidy: Cable management trays under desk help hide messy cords and cables, keeping your workspace organized and enjoying a cable-tangle-free, clutter-free work environment. Sturdy & Stable: The under desk cord organizer is made of carbon steel, which is hard and wear-resistant. Therefore, when the under-desk cable manager tray is properly instal, it is stable and capable of carrying a weight of about 18 lbs - 20 lbs, enough to support a large number of outlets and cables. (Note: the connection of the two trays must be screwed in the screw holes.) Hollow Structure Design: The under desk cord management tray hollow structure design can effectively reduce dust accumulation and better fix the cable while maintaining good air permeability, high heat dissipation efficiency, and avoid overheating of the wire or power cord.
