How to Pick Between the Micro and Jumbo Ultra Fab Trailer Rollers

Question:

Hi, hows your day going? I cant decide between the two, the micro or the jumbo. Does the micro have the same bolt diameter? The jumbo is around twice as heavy, do you think the micro might be underrated for a 24foot enclosed trailer? Thanx.

My day is going great, thanks for asking.

The biggest factor to consider when choosing between the micro roller part # UF48-979021 and the jumbo # UF48-979023 that you referenced is the overall height of the two.

The micro measures 2-1/4 inches tall and the jumbo is 3-1/2 inches tall. Depending on where you would install the roller and how much height you would need to prevent other portions of the trailer from dragging is how you would pick between the two. Neither really have a weight rating so it's best to go with the one that would work the best on your trailer. If you have a very low ground clearance the micro might be a better option, whereas if you have a higher amount of ground clearance the jumbo might work better since it would help prevent other portions of the trailer from dragging.

Basically the jumbo will work better, but if the ground clearance is low enough that you are dragging all the time the micro would be better since that way the roller wouldn't be contacting the ground all the time.

I attached review videos for both rollers for you to check out as well.
