Made of pure white Silicone Rubber, durable and corrosion resistance.
Can accept multiple wires from any direction and can pass through any cable up to 0.8 inches (diameter)
Protect cable and wire from sharp corner or edge of holes, keep desk clean and tidy, it is also a good decoration for holes.
Simply drill a hole(Suggest Diameter 15/16″/24mm), place the main body of the grommet directly into the hole.
If you have an existing 1″(Diameter25.4mm) hole, then you may need tape wrap outside wall little bit or put glue on the wall to make it tight.
It is still clean since the lip will cover the tape if you wrap it well.
