Loading a boat solo or in windy conditions? We've all had those moments where things don't line up quite right. The spool design guides the bow into place smoothly, even when conditions aren't perfect. It takes the pressure off and helps everything feel a little more under control.

Video Transcript for Review of Caliber Boat Trailer Parts - Rollers - CA75AJ

Hi, everybody, Steven here with etrailer.com. Let's take a look at our Caliber three inch spool roller for the boat trailers, and it's got a half inch shaft and it's a nice sturdy rubber. Now, folks, this replaces your dry rotted or a cracked bow roller, and it supports the keel of the boat while it's on the trailer. It's ideal for flat bottom boats, and is made of natural rubber, so it's gonna absorb shock while you're towing, it's UV resistant, and it can hold up in the sun. Now, some quick dimensions on this guy. Overall, the diameter, I got right at three inches.

Keep in mind it is rounded on the edges, so I got right at three inches. And the shaft, about a half inch. Now, when I measure from side to side on this particular one, I got about three and 3/16 of an inch, maybe three and 1/8. So keep in mind, this is technically a three inch spool roller, so it will fit that three inch application on the center roller bracket just fine, okay. So there are some variances there in the rubber, and that's totally normal.

Well, folks, that's gonna wrap it up. I'm Steven. Thanks so much for your time. Have a good one.

See what our Experts say about this Caliber Boat Trailer Parts

  • How Do I Know Which Bow Roller To Go With?
    Hello Aaron, thanks for reaching out. Are you replacing old rollers? If so we would just want to make sure the replacements are dimensionally the same, or at least very close to the same size as the originals. The 3" wide rollers like part # CA85AJ are a fairly standard size. They will fit a 1/2" shaft. The TPO is generally considered more durable than PVC or rubber so these are a great option that will work great in any climate. If you need a different size roller just let me know....

  • What is the Difference in the Caliber 3" Spool Rollers?
    Hey Aiden! The main difference in the Caliber 3" Spool Rollers you were looking at is color and what they're made of. They all fit a 1/2" diameter shaft. The Caliber 3" Spool Roller for Boat Trailers item # CA52AJ in yellow and item # CA25AJ in blue are both made of PVC. They're going to be more flexible and soft but won't last as long as others made with rubber or TPO. The Caliber 3" Spool Roller for Boat Trailers item # CA75AJ is made of rubber and is just your standard replacement...

  • Will the Caliber 3" Spool Roller for Boat Trailers Work as a Replacement for My 3 1/2" Rollers?
    Hello RM, Just as long as you shaft is a 1/2", then these will work fine. Yours were 3 1/2" long and the Caliber 3" Spool Roller for Boat Trailers - 1/2" Shaft - Rubber - Black # CA75AJ are actually 3 3/16" long. What kind of boat do you have?
