Hello Elijah,
We don't have any way of knowing specifically what seal is needed for the slide out on your 2021 Forest River Cherokee 5th wheel, so to determine what you need you'll have to measure your current seal and find a match.
For example, the Rubber Wiper Seal and Bulb for RV Slide Out # SR48FR is 3-3/16" wide overall, while the bulb portion is 15/16" tall. These are commonly found on Forest River 5th wheels but you'll want to measure to make sure it's right for yours.
If that isn't correct, I have added a link below to our entire selection of seals, which you can filter through by size.
