These grommets worked perfectly for running wire through the firewall on my drag car, super easy to find the correct size, super durable and easy to cut the cross material to run the wire through

Seem to be of good quality. Very useful.

Nice selection of grommets, soft rubber, and also they are not only different sizes, there are ones for different thickness of material the grommets are going into, added bonus

Keeps wires from getting chafed by sheet metal

Installed as well as one could hope for being under a dash, material the grommets are made from is pretty thick should hold up well! Fit three, 4 gauge wires through the largest size with some room for at least 1 more. Love having varying sizes as there are some other things that could use grommets!

Great assortment.

Seem to work fine, time will tell if the rubber holds up
