Keeping your wires safe from damage is a breeze with the Wire Loom, 3/8" Diameter, 10' Long by Hopkins. This loom is designed to shield your wires against road debris and sharp edges, ensuring a long-lasting protective cover. Whether you're rewiring a trailer or organizing under-the-hood circuits, this loom provides a tidy and secure fit over your wires.
The pre-split design of this wire loom simplifies the installation process significantly. No more threading wires through a narrow tube—just open the split, insert your wires, and let go. It holds your wires snugly without the need for additional tools or effort, making it the perfect solution for both professionals and DIY enthusiasts.
With an inside diameter of 3/8" and an outside diameter of 1/2", this wire loom is ideally suited for most standard wiring jobs. Whether you're dealing with a single 3 gauge wire for a winch or typical 4-wire trailer setups, this loom offers ample space to prevent overheating and ensure neatness in your wiring projects.
Pairing this wire loom with 1/2" clamps, such as part # A0500, provides secure and stable integration with your existing setup. Perfect for ensuring the loom stays in place, especially in areas where movement could expose wires to sharp edges or friction. This way, you maintain a clean and professional appearance in your wiring.
Whether you're restoring an old boat trailer, organizing wires in your Jeep, or setting up a new lighting system for your trailer, the Hopkins Wire Loom has you covered. Its durable construction and reliable protection make it a staple in countless wiring projects—from the garage to the workshop.

Jeff: Hello, everybody. This is Jeff at etrailer.com. Today we're going to take a look at this Hopkins, 10-foot long, three- eighths-inch diameter wire loom. Now this is a split, convoluted three-eighths-inch diameter wire loom that'll easily slip over your wiring and protect it from any damage or the elements. It has a nice plastic sheathing. And if you notice it is split down the whole 10-foot length of the loom.
It has an inner-dimension of three-eights of an inch, outside dimension of a half an inch. And I just wanted to show you what you would use this for. Here's an example of a plug that would plug into a light on your trailer, and then you'll have your wiring come out of that. So if you want to protect that wiring, what you can do is just find the split portion, and then just go ahead and insert your wiring all the way into that split portion.And you could go as far as you want, you can go the whole length of wire, or you can just go part of the way and you can see once you get it in there, it'll protect the wiring, the section you need it to. And again, if you have to go more just to go ahead and pry it apart, and then just slide your wiring in there.
And again, that goes all down your wiring to protect from any damage. But that should do it for the review on this Hopkins, 10-foot long, three-eighths-inch diameter wire loom.
Product worked exactly as advertised
Ordered 3 items needed to do a compressor/air springs install on my 2021 GMC 2500HD. Dealing with etrailer was seamless and I really liked having the ability to chat with a tech to confirm I was ordering the exact parts needed for my rig. Highly recommended !
As usual, etrailer provide exactly what I needed almost immediately! Excellent instructional videos as well!
3/8" Works fine for 4 wires. 1/2" or 3/4" will be better for larger bundles. Used on my 20' Car Hauler trailer.
Works as expected. Good quality and has held up well thus far after a year being installed on a boat trailer.
I bought the whole package for.my caravan and it was simple. product is supreme and videos on line gave me direction saving a lot money doing it myself. lifetime customer
One year ago, I installed the wire loom to contain and protect the trailer light wires on my newly restored 1969 boat trailer. They provide a professional finished look to the wiring job. They were easily installed from connector and down the frame. I would recommend and purchase again.
Excellent Product. 1 year under my pickup and looks new! Doing its job.
Thanks for the great customer service and quick shipping. Going to install this weekend
Thanks again
Great for organizing wires. Good quality loom with split to help make the installation easy. The split stays closed but I also periodically wrapped it along the length with cable ties and to attach it to structure to make a neat install. I keep a stash in different sizes so I always have something on hand for various wiring projects.
Excellent item. I just thought the price was a little high for the guage wire you get with the harness. I definetly like the idea of not having to run wires over the top of the car. Watch the you tube video to get how to route the wires to keep them away from any moving parts. Also order 35 ft of 3/8' wire loom item # 39035 to help protect the wires. Installed this item on a 2014 Honda CR-v EX. Very east to install.
Perfect solution for protecting trailer wires.

All the products are fabulous!! Thanks for following up with me. They are in use regularly.
I bought this to cover a 5 wire brake light harness. Wish I went a size bigger for 5 wires. Should work fine for most 4 wire harnesses. Good product. Performs as advertised
Used this on a trailer re-wire project to protect trailer light and brake wires. Works great.
All items in the order for trailer wiring components were exactly what I ordered and all items were delivered promptly. Good communication from Etrailer with reasonable prices, and FREE SHIPPING!! Nice.
Restoring a 1991 2 horse trailer. etrailer had all the exact lights made by Peterson, 35 years later.
I can only really say that this wire loom does its intended job.
Keep in mind, if you intend to put more than 3 wires in it or hope to fit wire splices into it, size up to a bigger diameter.
I used a closed end socket wrench to force the wire into the split as the loom was pretty stiff
What can I say...it’s a wire loom. Does what it’s supposed to do. Seems to have held up just fine. The trailer I used it on is stored inside so I cannot speak to UV resistance.
Bought to use with 4 pin wiring! Oops, to small!

Kip, thank you for your review. If you are looking for a larger diameter wire loom I recommend part # 459075-1. This wire look is 1/2 which is the size we normally use on our installs.This is sold by the foot, to get the length you need.

As always Etrailer has come through. My order to completely wire my boat trailer came as promised. I've ordered several times and have always been completely satisfied. Thanks Pat
Worked for re-wiring of trailer lights.
Product promptly dispatched and received, as described. Thanks, etrailer!
worked out well for my 4 wire harness. could have been a touch larger dia.
Appreciated the easy ordering and the very quick delivery. Ordered on Thursday evening and received the order on Sunday afternoon with the standard basic shipping. When ordering I was told the shipping might take 2-3 weeks but it came in 3 days.
