The grommets are made from durable black PVC (Polyvinyl Chloride).
The box contains a total of 250 pieces.
Wiring grommets have an opening in the center to allow cables to pass through, protecting them. Blanking grommets are solid and are used to cover and seal unused holes in panels.
The set includes 7 sizes of blanking grommets (for hole diameters 6.4, 9.3, 12.3, 15.8, 20.0, 25.0 mm) and 7 sizes of wiring grommets with specific hole and inner diameters (e.g., 6.4 x 4.0 mm, 9.3 x 7.7 mm, up to 25.0 x 19.5 mm).
While PVC offers some weather resistance, prolonged direct exposure to harsh UV rays or extreme temperatures is not recommended without additional protection, as it may degrade the material over time.
Yes, PVC is an insulating material, providing electrical insulation for the wires passing through the wiring grommets.
It is best to store them in a cool, dry place, preferably in their original packaging or a compartmentalized box to keep the different sizes organized and prevent loss.
Verify that you are using the correct grommet size for the panel hole diameter. Ensure the hole is clean and free of burrs. If the hole is slightly too large, consider using a grommet one size up or a suitable sealant.
Ensure the cable diameter does not exceed the internal opening of the wiring grommet. If the cable is slightly large, gently flex the grommet opening or use a lubricant (like silicone spray) to aid insertion. Do not force the cable, as this can damage the insulation.
Ensure the hole edges are smooth and free of sharp burrs. Use gentle, even pressure during installation. If using a very tight-fitting grommet, a small amount of mild soap solution might help, but avoid excessive force.
Setup: To install a grommet, select the appropriate size for the hole in your panel and the cable you intend to pass through (for wiring grommets). The grommet typically features a lip that sits on one side of the panel. Flex the grommet slightly and push it firmly into the pre-drilled or punched hole until it snaps into place and the lip is seated. For wiring grommets, carefully insert the cable through the center opening after the grommet is installed in the panel.
Compatibility: These grommets are designed for use with standard sheet metal panels and electrical cables. Ensure the hole diameter in your panel matches one of the available blanking or wiring grommet sizes. The internal diameter of the wiring grommets should accommodate your cable without excessive force, preventing damage to the cable insulation.
Care: Clean grommets with a damp cloth. Avoid using harsh solvents or abrasive cleaners, which can degrade the PVC material. Store the grommets in their original packaging or a compartmentalized container to prevent loss and maintain organization.
