Today, we're going to be taking a look at part number 382385UB. This is the U-bolt kit for trailers with square frames. These are going to be perfect for boats, snowmobile and standard utility trailers. They can be used for many different applications when it comes to attaching your items to your trailer frame. These are going to be made from a metal construction, and they're going to have a nice, zinc-plated finish on it, so they're going to resist rust and corrosion. You're going to get two U-bolts.
You're going to get four flat washer and four lock nets. The square bend here on the U-bolt is going to simplify the attachment of your hardware to your square trailer frame. We're going to take a look at some of the dimensions real quick. Starting with just the length of the threaded portion, that looks like it's going to give us a measurement of about 2 1/8". From the bottom of the threads to the inside edge at the top portion right here, that's going to give us a measurement of 5 1/4". The opening that we have in between the down portions of the U-bolt, that's going to give us a measurement of about 2 3/8".
Then, center on center, the distance that we have between the studs, that's going to give us a measurement of about 2 11/16" of an inch. The diameter of the U-bolts themselves, those are going to measure 3/8". Again, they are designed for square trailer frames. That's going to do it for today's review of part number 382385UB.

Just what I needed to upgrade by boat.
etrailer shipped fast and product was just what I needed but no nobody else seemed to have.
Quality product and quick shipping than ks
Typical u-bolt, but these guys always have the off sizes no one else stocks!
That is why i always purchase here!
Always prompt shipping at great rates
Worked perfect to bolt a tool box on the front of my trailer on the 2x4 frame.
I received exactly what I ordered and in a timely manner. Great company and excellent customer service.
I ordered a bolt square head u-bolt that I couldn't source locally. I needed a particular size as I am building a custom motor mount for s kayak.
Just as always great price great product and the shipping is out standing. It doesn't take long to get any thing from them even on the west cost standard shipping I could get it in a week most of the time.
Having to redo totally my Pontoon boat trailer. I needed some advice, called in and spoke with an Engineer to narrow my options. Very helpful.
I was able to order parts and get them within one (1) week. Good job guys
these u bolts are just what I needed. could not find them anywhere local. I am using them to install an extra brace on my boat trailer wind guides.
ARRIVED ON TIME VERY GOOD QUALITY
My order was filled as requested and received on time. Products I received were good as I expected them to be. This was my first order with etrailer and I will shop again if the need arises.
The products I ordered were for making the tongue on a boat trailer. They worked as expected.

Great
The roller and bracket for my boat trailer came in a few days before I was expecting them. A pleasant surprise indeed.
Parts was exactly as described and fit my boat trailer perfectly.
I am very pleased with the assistance I received from the person that took my order along with their service.

Very good
my trailer is back up and on the road ... thanks.
Bought 2x packs of u bolts kits.. 3x of one type nuts in one of the packs and 4x nuts in other pack and one other nut in first packs cheesy dent type lock nuts. Horrible, I expected more from this company.
I was able to take an OLD trailer from an old barn from 50 years ago and
re-do the axle. The "u" bolts worked. I find it interesting that
rectangler bolts are called "u" bolts. - so funny
Either way - the U-Bolts worked for me. Nicely done by ETrailer.
Product was delivered within reason and I sent "seller" picture of
finished axel. --
