Video Transcript for Checking Out the Trailer Square U-Bolts (Qty 2), 2-3/8" x 5-1/4" x 3/8"

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.

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.

The roller and bracket for my boat trailer came in a few days before I was expecting them. A pleasant surprise indeed.

my trailer is back up and on the road ... thanks.



by:

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.



by:

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. --

  • How To Mount RC Manufacturing Trailer Tongue Tool Box 350970 Without Drilling Holes In Frame
    Since you are not wanting to drill all the way through the aluminum frame on your H and H trailer, you can use U-bolts like # CE15283GA-2 to go around the frame of your trailer, and up into the RC Manufacturing T-Series Trailer Tongue Tool Box - A-Frame - Aluminum - 2.6 Cu Ft - Silver # 350970 to mount it. The # CE15283GA-2 are galvanized so the will not rust, but you will want to make sure they are large enough for your frame rails. These U-bolts measure 3-13/16" long and 3-1/16" wide,...

  • Square U-Bolt Kit Needed for Adding Unistrut to Trailer
    Hey Ron, thanks for reaching out! The closest U-Bolt kit we have to the specs you're looking for is the Trailer Square U-Bolts # 382385UB which measure 2-3/8" x 5-1/4" x 3/8". We don't have a massive selection of square U-Bolts though, so if you have to have those exact specs then you might be better off visiting your local hardware or home improvement store to see if they have what you're needing. What are you planning to use the Unistrut for?

  • Hardware for Redline Bolt-On Trailer Fender Brackets
    We don't offer bolts that fit the bracket perfectly that will fit around your rather tall trailer frame. If it's not a boat trailer, you might be able to use the # 382385UB U-bolts. The bolts are 5-1/4 inches long, so they'd be tall enough to fit around your trailer frame, but they span 2-3/8 inches, so you'd need to drill a hole in the bracket to accommodate the U-bolt. If it's a boat trailer, or you'd rather not drill holes in the bracket, you'd probably want to use a galvanized U-bolt...
