Power Strip Clamp Mounts Securely on Your Desktop without Drilling This clamp-on holder for power strips and surge protectors is easy to install without the hassle of drilling into walls or workbenches. Keep AC outlets and USB ports within easy reach of your desk, table or workspace by attaching the CLAMPUSBLK to any flat surface 0.4 to 2 inches thick. No tools are needed. Just slide the clamps onto the surface's edge, tighten the adjustment knobs by hand, and snap your surge or power strip into the mounting clip. No More Crawling Under Desks to Plug Devices into Hard-to-Reach Outlets Add AC and USB power where you most need it. The CLAMPUSBLK lets you install a power strip or surge protector within an arm's reach of your chair. The heavy-duty plastic clamp accepts most strips 1.6 to 2.4 inches in width. Soft EVA foam pads on the clamp protect your desk from scuffs and scratches. Retrofit Existing Installations to Improve Access to Outlets Add AC outlets and USB ports somewhere new or change the mounting of an existing power or surge strip to improve access to power. A cable management clip in the rear keeps power cords neat and tidy.
