The Eaz-Lift slide out supports help protect your RV's slide out mechanism by providing support to your slide out room when it is in use for prolonged periods. The universal fit top will support any slide out rail, and the space saving handle and tethered pin make the support easy to use and store. The Eaz-Lift slide out support adjusts from 19" to 47", with incremental locked positions, plus minute adjustment that extends an additional 14". These durable supports are constructed of rust-resistant steel and support up to 5,000 lbs. each.
