Questions & Answers

This firewall boot has a hole through it, or is it blind through it. To make my own hole in it, I'm looking for one with a hole already cut out. Is that okay?

The answer is yes. If you would like the hole to be larger, you can trim it back. It has one or two small holes about 1/2 inch wide

Can you provide one that fits a hole in the firewall of 2 inches?

It's too big for the 2" hole we have

When the grommet is facing the right way, what will be the effect? Do you face the engine compartment from the flat part?

Basically, it has two elbows that go through the engine compartment wall as grommets and seal both ends. If the length of your wire bundle requires cutting of the small end, do so. Wrap a zip tie around the boot and wire bundle to keep them in place.

The 2017 Ram 1500 comes with a wire entry
5/5

In my 2017 Ram 1500, I used this to bring in wiring. Using a 1-inch drill bit, I drilled Add this firewall boot to the clutch delete plate after creating a 1/4" hole in the plastic plate. I was able to install it nice and clean.

Here's an update! This is a good wire for multiple small wires, but not so good for large wires like 1/0 awg and beyond
4/5

My chevy's NBS firewall had no 1/0 wire so I purchased this so I could run 1/0 power wire through it, but you can run LEGIT 1/0 power wire through this if you cut the first two nipple ends But that's about it, the picture doesn't do a very good job of showing you how small or big this is (it's definitely I think this is more suited to people who want to fish for 24 hours at a time If you used this small wire, you could fit about 15 to 20 small wires through it, but you won't be sending more than 1 1/0 wire and maybe 8 to 10, so I'll probably return it and go with the Scosche WPG0-. Ten firewall boots come in a pack for ten dollars and they have a waterproof surface. Although this piece of molded rubber could be more affordable since it is a piece of rubber, 16 dollars isn't a big deal to In the next few minutes, I'll show a picture that has 1/0 beside it. Update I went to lowes and purchased a dishwater connection hose adapter that is like $5 and is the exact same thing, and you can find it at lowes or home depot for that price. To me, 15$ is an absurd cost for a rubber piece.

If you have a JL Wrangler, it fits perfectly in the firewall hole on the driver's side
5/5

In the case of a JL Jeep Wrangler with an automatic transmission and you want to run some wires through the firewall on the driver's side there is a cap fitting where the clutch would normally be. You can drill a hole through the cap and run your wires through it if you remove it. As an alternative. This ridiculous rubber boot looks like it works perfectly if you don't mind throwing the cap out. The application seems to work fine for me! It fits from the top part of the shaft up to the smallest portion. While it looks goofy, I still like it.

It's a pretty cool animation
5/5

In addition to making a secure and protective passage from the firewall into the engine compartment, this thing is also weatherproof and chafeproof. My boat and truck each have two of these, and I bought several of them. In order to create a waterproof and secure transition to the engine compartments and battery storage areas, we used these straps. It is extraordinary that all you have to do is cut off the material at the thickness / diameter that you desire. To transport the 1"OD plastic conduit through the 1" diameter cut out, the boat used the 1" round cut out. My goal was to prevent chaffing and to make a water-proof transition with it. I really liked how this worked! In the other boot, I ran the 6 gauge battery cable from my deep cycle second battery boxes on my roof rack through the roof rack so I could charge my aux battery batteries. Auxiliary battery box is used to run a DC/DC power converter at 12 volts. NOTE this device has storage for many sizes of cables, so you may not want to use it for small cables. There are about 6 inches of it (average) and you have to drill a 1 1/4 inch hole to mount it "properly & securely". Assuring your security". Once you've done that, the software is incredibly The hole doesn't have to be attached, but I applied a little weather striping adhesive to help hold it in place just in case I made the mounting hole a little too huge. The note (Boulder The following is a description of the product. The shields protect wires from sharp edges and fit 3/8 inch, 11/16 inch, and 1 inch diameter wire bundles*. This chafing-free fastener prevents wires from being cut while in use
Its designed to work for wires, tubing, and air lines
Only requires a 1 inch hole. The hole has a diameter of 25 inches.

A brand new OEM boot! I just cut off an OEM one to remove the wiring for my auto trans, and this looks almost exactly the same
5/5

It will just take a little bit of time to figure out how to run what's left (Abs) All of this will prevent anything from entering the cabin and keeping it clean. My initial reaction when I saw these rubber boots for this much was "no thanks," but when I got them, saw them, and felt them in my hands, that was another story. It is clear to you That was close!.

I really like the fit of this
5/5

My new boot fits like a glove after I finally got around to installing it! On my 05 TJ, I needed to run some wires through the firewall for the off road lights. A plastic cover was found near the driver's side (USA) and was removed. It was just a matter of drilling out the center and inserting the boot. I highly recommend this product for its ease of use and reliability.

There is no easier way to do this
5/5

During my search on how to pass wires through my truck's firewall, I stumbled upon this solution. I was going to use a nut type fitting to seal off the engine compartment from the cab when I found So I gave it a shot because it looked so easy. I was amazed at how easy the install was. Using a stepped drill bit, drill a hole in the center of the There is a hole that measures 25". A simple grommet end was all that was needed to complete the project. The more I spent time finding a clear location, the more I focused. It took me about three minutes to install everything. After checking that there weren't wires or hoses in the way, it took two minutes. An additional half minute to drill a small pilot hole and to double check its position, and lastly to drill the 1 hole. There is a hole that measures 25". Moreover, I liked the fact that I am able to further expand it if required later. The request does not need to be resubmitted Another hole needs to be drilled. Simply thread the wires through and zip tie the end to prevent water from getting inside.

A grommet of this quality at such a high price scared me at first
5/5

I was reluctant to spend so much on the In my experience, single-spaced fonts work well Wire grommets that used to cost a dollar per item now cost just a penny. As part of my project, I had to run upwards of 8 wires of different sizes (18 AWG to 4 AWG). I was not willing to drill 8 holes for 8 wires. I am pleased with the quality of this product as well as the OEM stuff coming from It is important that the grommet is properly inserted before any burrs are removed from the hole you drilled. I was surprised to discover that I could use the middle size instead of the largest one after I did a test run. Make sure you test your wires before you cut the piece to size.
