onebadmonte Posted September 4, 2010 Report Share Posted September 4, 2010 Product: Monster 400 Series Heavy Duty Firewall Grommet Manufactured by: Monter Cable Purchased/recieved from: Amazon.com I'm in the works of a 3k Watt build. This a first for me. I've been scouring the net for the best deals on the parts required for such a build. Some of those deals have been once in a life time deals, but every once and a while there is one that I can share. This is one of those. It's hard to imagine Monster Cable products and good deal in the same sentence, but it's true. Normally one is left to his own devices when passing 1/0 gauge cable through sheet metal. I picked these up from Amazon.com My link I really couldn't find any dimensional info on them, so I took a gamble in hopes they'd work with my 1/0 radaflex welding cable. Luckily they sinched down on my cable no problem. They advertise corrosion resistant, which means plastic. I'd avoid putting them any closer than 8 inches to any exhaust components. Here are some pics. Fully compressed the inside diameter measured .570" at the smallest diameter and .620 at the largest diameter. Overall length was about 1.650" give or take. For the through hole I recommend a 1" hole saw. A little filing might be required. The hex on the main body is just over 1.250" Max diameter through the main body is .750" The compression nut measured just over 1.250" like the main body. The through hole on the compression nut measured .725" a bit smaller than the through hole on the main body. Looks like there is enough material on it that you could file some off if you needed it to be a bit bigger. Here is some info not pictured. Jam Nut Dims: Thickness .270" Hex Size across the flats 1.387" Max panel thickness this item can be used on is .250" Thanks for looking.

crunkjuice1 Posted January 6, 2011 Report Share Posted January 6, 2011 sorry for me being the dork to ask this but in the link to amazon if I add that to the cart will I get the two pack of grommets? Link to comment Share on other sites More sharing options...
cc_audio Posted January 6, 2011 Report Share Posted January 6, 2011 I have two dozen of these I pulled from some tanning beds I scrapped this summer. They fit Knu 1/0 perfectly, great little grommets which I'm sure you can find at the hardware store for less than Monster's high prices. It can be rough taking a hole saw to the firewall though. It's all gone! The Celica Build Feedback If I buy something from you, DO NOT USE FEDEX! Link to comment Share on other sites More sharing options...
crunkjuice1 Posted January 6, 2011 Report Share Posted January 6, 2011 Dang I just click purchase on other tab then came over to this hit refresh and saw your post turns out around $13 total. Good for me to pay that than short out 1/0 on firewall with my big ass feet on the cable by accident. And I use this to get the hole through firewall Link to comment Share on other sites More sharing options...

crunkjuice1 Posted January 6, 2011 Report Share Posted January 6, 2011 oh well guess I'll find out if what I purchased from the OP's link is the same as his first pic that shows two grommets as to those streetwires 1/0 that show only one grommet per package. Just looked it up parts express for two grommets $13.78 plus $9.98 for shipping. Thats why I'm crossing fingers the OP's link is like his first picture of two per package if thats the case then I didn't get poked to hard from OP's link with shipping at $12.53 for two.

The hell does post count have to do with anything? lol and if your fro SA you know we can find some good deals lol PEACE see you around!!!! As an update to this thread I just received the grommets and they are pretty beefy compared to the rinky dink one that come in rockfords 1/0 amp kit. I need to get my butt outside and get started on wiring my second battery. Thanks goes to the OP for such a good find. There might be better grommets out their but I can say these will definitely get the job done. Link to comment Share on other sites More sharing options...
