Features: This is a benchtop cable grommet in a three-piece design with two swivel covers. Made of ABS plastic with metal screws and a spring-loaded inner plate that can be rotated to reduce the size of the holes. Built-in anti-slip spring ribs, the hole is stuck, and the threading is very convenient. The cover surface insert can be embedded in the table to keep the table clean. The cover spring loaded portion can be rotated to allow multiple cables to pass through. The cover can also be removed completely to allow the cable with the electrical plug (most sizes) to pass.
