Illustrative guide, not to scale. Measure the hole diameter, the outside of your wiring loom and the thickness of the panel where the retaining groove will sit.
How to measure
- A · Hole size: Measure the diameter of the opening in the panel, in millimetres.
- B · Wire size: Measure the outside diameter of the complete wiring loom, including sleeving or tape. Not needed for a blanking grommet.
- C · Panel thickness: Measure the thickness of the metal or material the grommet clips into. This determines the width of the retaining groove.
Choose your grommet style and we'll use our standard design proportions for the remaining dimensions. We may contact you if additional fitment details are required.

Custom LM Wiring & Blanking Grommets
Designed for custom automotive builds, these made-to-order Lazaro Motorsports grommets help finish panel openings neatly and provide a flexible passage for wiring looms. Each grommet is made to the measurements you supply.
Available styles
Angled wiring grommet: An offset, angled outlet suited to wiring that needs to exit towards one side of a panel opening.
Centred straight wiring grommet: A vertical outlet positioned in the centre for a direct wiring pass-through.
Blanking grommet: A closed design for covering unused panel openings, with no wiring passage.
What we need from you
Choose the style and enter the panel hole diameter, panel thickness and, for wiring grommets, the outside diameter of your complete wiring loom (including sleeving or tape). Measurements must be in millimetres.
With Slot or No Slot?
With Slot allows the grommet to be opened and installed around an existing wiring loom. No Slot is a continuous grommet, requiring wiring to be fed through the opening during installation. Blanking grommets are supplied without a wiring slit.
Important fitment information
These are custom-made parts. Please measure carefully before ordering. Flexible materials and 3D-printed tolerances vary, so sealing performance is not guaranteed; additional sealant or testing may be necessary for weather-exposed applications. We may contact you to confirm unusual dimensions before manufacture.
