Where can I fine grommets with 1/8" groove and 3/8" &1/2" hole? Everywhere I ask all anyone has are 1/16". My frame is 1/8" thick and I'm running wires and cables inside the frame.
while i'm sure there are many good places to get grommets...i like to use this one from Napa. part # 784634......the ID is 1/2" (where the stuff p***es through), the overall OD is 1" , the groove is 3/4 OD (so you drill a 3/4" hole to install it) and get this...the groove is a full 1/8" wide other grommets i have seen at hardware stores are usually 1/16" as you have found out $4.29 for a pack of four
A truck parts place would have Grote brand parts, Grote sells all sizes being in the lighting business. I recently bought a couple of bags of ***orted sized grommets just to have a few extra's when needed.
