Today we're going to review and install the Spectro Snap Bushing, part number SWC8055. Note, the snap bushing is available in two sizes: the 7/16 inside diameter and a 9/16 inside diameter, part number SWC8057. Here's what our Spectro snap bushing looks like. This is a nylon bushing that will help protect our wiring as it passes through our pre-drilled hole. Typically that hole is drilled into sheet metal like a firewall. The raw edges of the metal can chafe or dig into the wiring or even an air line, and the snap bushing will protect it. Once the snap bushing is slid through your pre-drilled hole, the locks here will help hold it in place and the face of the grommet will be on the other side of the firewall, so we'll have part of the grommet on each side holding it in position. When drilling it out, you're going to open it up to approximately a 9/16 hole.
That makes the inside diameter 7/16 and the outside overall is 21/32. The grommet itself is 13/32 thick. Our grommet is typically used in areas where there's not a lot of heat, but it will hold up to approximately 257 degrees Fahrenheit. Now with the hole drilled out, we'll go ahead and take our snap bushing and install it. Put it in the hole, push it into place, and it locks into position. We're now ready to route our wiring, air line, or whatever you need to route through the protected hole.
There you have it for the Spectro Snap Bushing, part number SWC8055.

Will save wires
fit perfect. video was a big help
Absolutely Superb Service! On the 23rd of September at 10:10 a.m., I ordered a brake controller and several other items from the etrailer.com website. By 12:16 p.m. of the same day, I received a notification from etrailer that the order had shipped. The complete order arrived at about noon on the 26th. Ordering on the website was easy. All items were described very clearly and pictures were provided for them. The service at etrailer is absolutely superb. I would recommend this company, without hesitation, to anyone needing trailer parts or accessories.
You sent me the wrong size again
The fit was a bit loose in the hole I drilled, but the location wasn't perfectly flat. I used silicone sealant to secure it.
Everything I ordered came exactly as it showed them to be but it took one of them 12 days to get here and the other one only 4 days. I don't think that is the fault of etrailer I think it's a problem with the US Postal Service.
Timely shipping and part exactly as adv ertised.
Wish I had gotten a larger one. Had to make an additional hole in the firewall due to the small size.
We put it on a 2009 Silverado crew cab. Works great but would be better with 3' extra wire. Would have brought wire through the firewall but had to drill a hole in the floor.
