In this video, I replace worn secondary rubber seals on our 10-year old Keystone Cougar trailer’s main slide-out room. I show how to install the new slide seal and discuss sourcing it and the other slide seals, such as the 2″ wiper seal.

The job is very straightforward, involving removing a few screws and plastic corner flashing covers and recaulking a few seams.
