Default metal edge protection

What do you call the product that some install on the edge of sheet metal, say in a lightning hole where wires or ducting pass thru to protect the parts from being cut by the metal edge. It looks like a strip of white plastic with lots of notches to allow it to flex and be put on the inside of a circle cut out.
I have some on the RV-6 I bought and would like to buy more but don't know
what it is called or where to buy it at?
can anyone help me?
Thanks

Grommet is the general name.

Also, "Edge Grip", "Trim", "Plastic edge trim". Try McMaster.com

Default Just a heads up,

This stuff comes in different sizes to fit different thickness of metal.

The -1 is for the thinnest, higher -# is for thicker, check the chart in the link I provided earlier.

I had to use -2 for some of the wiring in my ten.

Exclamation Two different types of edge...

...protection are being discussed here, and not identified well...

The link above is to the more usual, and cheaper, edge protection that looks like a u channel with slits cut in the side. It is a single plastic (or nylon or polyethelene) extrusion/molding.

http://www.gen-aircraft-hardware.com...df/ms21266.pdf

The Aircraft Spruce link (post #2) above is much more expensive due to a very different construction method. As described at Aircraft Spruce...

The product is a composite of polymer encapsulated spring stainless steel enhanced by a protective cushion.

It will grip the edges of the metal and will flex in a much tighter radius.

This spec. sheet has better visuals than AC Spruce...

http://www.devicetec.com/DTIProducts...92Brochure.pdf

I find the cheaper "catapillar" plastic ones (in nylon) work fine on large lightening holes, etc. - but if you want edge protection on a portion of a straight edge, or are dealing with complex cut out shapes, then nothing can beat the more expensive AC Spruce product.

They are vastly different products that perform similar functions.
