Slide out topper roller rubs slide out

[F4Gary]

My slide out topper rollers rub against the slide and has caused the bedroom slide to hangup on it and it pulls the slide up slightly and stops. If I reverse a little then it will continue all the way out. How much of a gap should there be between the top of the slide and the roller? There is about an 1/8th of and inch at the ends, and it rubs in the middle.

I sprayed some silicon on it and that helped it not hang up.

You don't want it to rub so what ever is needed to correct the issue, do it. Sounds like you need to space out the mounting away from the slideout wall to prevent the tube from burring. Good luck and keep us posted.

When my topper was running to close to the slide roof I found out there was a lot of slop in the mounting hardware. I replaced the mounting screws (oversize) and removed all of the movement so the clearance was at maximum.
