3/16" Inside Diameter Rubber Grommet - 1/4" Groove - Fits 5/16" Panel Hole

Product Overview:

3/16" Inside Diameter Rubber Grommet - 1/4" Groove - Fits 5/16" Panel Holes. Ideal for passing wires through panels without risking damage or abrasion by acting as a protective barrier, extending the lifespan of your cables and wires.

Dimensions:

• Inside Diameter: 3/16"
• Groove Width: 1/4"
• Groove Diameter: 5/16"
• Outside Diameter: 7/16"
• Thickness: 3/8"

1) Inside diameter - what passes through. 2) Groove width - must equal your panel thickness. 3) Panel hole - the drilled hole the groove snaps into (the Fits size). Get all three right and the grommet seats like factory.

• Measure and Cut the Hole: Pick a grommet whose inside diameter clears your wire or cable, then drill the panel hole to the grommet's "Fits" size and check that the panel thickness matches the groove width (both are in the Specifications table).
• Prepare the Grommet: Ensure the rubber grommet is clean and free from any debris. If necessary, lightly lubricate with a silicone-based product for easier installation.
• Insert the Grommet: Gently press the grommet into the hole, starting from one side and working your way around. It should fit snugly without excessive force.
• Thread the Cable or Wire: Once the grommet is securely in place, thread the cable or wire through it. The grommet should provide a protective, snug fit around the cable.
• Final Check: Ensure the grommet is seated properly and provides a tight seal. Adjust if necessary to avoid any movement or chafing of the wires.
