The product was exactly what I ordered and matched the website's photos perfectly. The brackets I ordered are durable, and of excellent quality for my application. When I placed my online order, the web site showed that the quantity I wanted was in stock, but that turned out to be incorrect. To their credit, they immediately called me to let me know, shipped what they did have in stock, and followed up every few days with status on the order balance. I was not charged until my order had been filled, and all of the brackets were in my possession. I highly recommend this company. 566000


Comments

What kind of company contacts you one year after the sale to see if you are still satisfied with their product? etrailer did. Great customer service and yes, the brackets I bought from them were put to immediate use, still look brand new and are as durable as they were on the first day.

The u-bolts I purchased are nice but I think all sizes should be available in stainless steel and come with bolt plates. As for customer service it could not be any better! Tori and Leslie both went above and beyond to make sure I got what I needed to complete the job. These ladies should be given raises for what they probably have to put up with on a daily basis! Thanks... 497275

Product seems pretty good. Really the only thing I don't like about them is it doesn't have any type of max torque spec on the package. I would guess about 30 foot pounds based on other online research. It would just be nice to have it on the package. 615118

These square ubolts are exactly what I needed. They appear to be durable and I like that they come with washers and nylock nuts. Faster delivery than expected. Very satisfied with this order. ?? 480862

Looks to be a great set of u bolts and they even came with nylon locking nuts whereas all the other bolts I looked at only came with split lock washers. Thats a real plus. Looked a lot of other places before I could locate the proper size. Thankfully etrailer stocked them. 456111

I had an emergency need, after attempting some modifications to a new canoe trailer, and eTrailer stepped up and quickly turned around my order the same day, enabling me to take care of my issue and be on the road as planned. THANK YOU!!! 191427

I used these U-bolts not on a trailer but to secure the front spring on my '32 Ford. 2-1/4" is the perfect width to fit the cross-member of the frame, and 4-1/4" is the length I needed to accommodate spacers between the spring and the frame for additional ground clearance. They worked out perfectly for this application. 190664

These were bought to replace the same rusted parts on my trailer. I had trouble finding them, even on your site, but finally came across them while searching for spring seats for my new axle. They fit perfectly, just what the doctor ordered. 48951

Do you have a question about this Boat Trailer Part?


  • Can Pack-Em Rack for Open Utility Trailers Part # PK-6-OP1 Fit a Tubular Frame Trailer
  • My contact at Pack-Em advises that their Rack for Open Utility Trailers, part # PK-6-OP1, can mount to a trailer that has a (round) tubular frame rail. Since mounting hardware is not included with this item you have the options of drilling into your trailer frame to install the two towers with your own hardware or using u-bolts to attach them to your trailer rail, which would avoid the need to drill your trailer. The two main C-channel upright towers measure 2-inches wide x 1-inch deep. We...

  • Diameter of the U-Bolts in Replacement Safety-Chain U-Bolt Kit, # C113
  • The Replacement Safety-Chain U-Bolt Kit, # C113, has u-bolts that are 9/16 inches in diameter, too large to fit through a 3/8 inch opening in a chain link. U-bolts # 382144UB have a 3/8 inch diameter.

  • Availability of Metal Trailer Wheel Step with U-Bolts
  • I may have a solution for you, however we don't have a metal plate available with pre-drilled holes that are spaced to match the Redline Square U-Bolts # 382144UB. If you are looking to attach a step to the fenders on your trailer we do have the CE Smith Galvanized Steel Step # CE26212G-15284GA that's designed for a 2 inch wide frame. This kit consts of a 12-gauge galvanized steel step that will connect to the frame via the included U-bolt and attach to the fender to provide you with...
