What is this?
These are the grommets used to cover panel holes. Rubber grommets grip wires and cables passing through holes, keeping them secure while protecting them from cuts and snags. The rubber grommets are mainly used to protect cables or wires from being scratched by electrical boxes and some wooden boxes. They are widely applied for hole plugging, outlet sealing, and other industrial equipment.

Are there any advantages of the product?
Made of silicone rubber material, the grommet is flexible and durable, with high temperature and corrosion resistance. It is waterproof, dustproof and has strong insulation, which is safer to use.
The unique buckle design fits the hole better so that it is easily secured for better wire protection.

How to use it?
No special tools are required, just choose the right size or drill a suitable hole in the box, attach the rubber ring to the hole and let the wires pass through.
