eTrailer had the parts i needed at the best price I could find after researching numerous places. The order was practically shipped immediately and arrived within a few days. They even followed up byu email to confirm delivery and to make sure I received exactly what I wanted/needed. 461533

Exactly the parts I was looking for, and for a price that couldn't be matched. The cost with shippping was less than just the parts at other places. I ordered 3 rubber bumpers for the tailgate of my toy hauler, along with the necessary mounting hardware. Shipping confirmation the same day. I kept checking the shipping tracking number and expected the package in about 8 days. It actually arrived 2 days early. (economy shipping chosen) Great service from etrailer. 423478

Everything came in as advertised. Purchased CE Smith bolsters, u-brackets, lag screws and carpet. Added two bunk boards to my Lowe trailer (Karavan). Only had two boards and I wanted extra to support the weight of the boat. Everything assembled easily. My boat loads easier and trailers better. Plus I have the piece of mind of having 4 boards vs 2. 402664

I used the ss hex lag screws and CE Smith swivel brackets to replace the bunk boards on my bass boat trailer. Both items have performed well with no issues. I expect to get years of service from them. I have purchased many products from Etrailer and have received excellent customer service and timely delivery. 310990

Ask the Experts about this Fastenal Accessories and Parts

Do you have a question about this Accessories and Part?


  • How Many V-Wing Brackets Are Needed To Support A 28-ft Long Pontoon Boat
  • I contacted the manufacturer and one V-Wing Bolster Bracket, Item # CE26244G, should be placed at each frame cross member. Mounting hardware for these brackets is not included so I recommend using a screw and washer like our 3/8 Inch Stainless Steel Hex Lag Screw, Item # FA74521, and Stainless Steel Washer, Item # FA0152661. I have attached a video for you to check out.

  • Thickness of Redline Rubber Bumper
  • The Redline Rubber Bumper # 385800 is not hollow so there is no "thickness" measurement to be taken. It has a 2-1/2" diameter, a 1" height, a recessed dimension of 1/2" x 1-1/8" and a mounting hole of 3/8". You would need screw # FA74521 and washer # FA0152661 to mount it. I've attached links to video reviews of this product for you to take a look at.

  • V Mounting Brackets to Convert Conventional Trailer into Pontoon Boat Trailer
  • The V mounting brackets that you could use to convert your conventional trailer to a pontoon boat trailer are the CE Smith V-Wing Bolster Bracket, # CE26244G.
