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. Hit the reply button below and I will get back to you.

Hey Aaron, did you decide to go with the TPO rollers for your trailer? I'm curious to know how they worked out for you, as it could help others looking for durable options.
