Handy Grommet

Some of you DIY's might find this a good way of passing large amounts of wire, battery cables or air lines through a body panel. It is a "Glad-hand seal" used in airlines on tractor trailers. The center hole is about 5/8" and can be made a little bigger while still providing good protection. They are available at any place that sells truck parts and are very cheap to buy. (Don't buy the urethane type).

You will need to make a 1-1/16" hole with a hole saw.

Re: Handy Grommet

Any sort of cushion between wire bundles or a line of some sort is always best when running through a thin metal wall like body sides etc etc. This is a great suggestion and one I've followed for so long now I forget when I first started doing it.

Smaller grommets can be found at Lowe's or Home Depot in little packages that suggest the size drill bit hole to use too. I'd also suggest once you've drilled through a factory painted bulkhead or other such panel treat it with a rust preventative since you've effectively pierced the protective envelope applied at the factory long before the van or vehicle was even painted.

Great idea------thanks for sharing!
