Question:

Sirs My c channel measures 13/16” The SR37FR description doesn’t include the channel measurement, only the outer dimension. I’m concerned the fitment will be loose. Do you sell a D Bulb seal that fits a Sierra 2019 Forest River 3875? Thanks in advance.

Expert Reply:

The channel on the # SR37FR would be approximately 1/4" too large so you'd want to go with the Rubber Bulb Seal for RV Slide Out - 1" C-Channel # SR84FR instead. This bulb will fit much closer to your 13/16" channel. I do recommend drilling a small hole every few feet through the outer bulb and using a screw to secure the base of the bulb seal to the track once in place.
