The Elegator Utility Trailer Gate Lift is a heavy-duty spring system that counter-balances the weight of a trailer's gate and/or ramp, thus greatly reducing the effort and strain required to lower and raise it. The system can be mounted either inside or outside of the side rail, is designed to accommodate both rear and side gates, and is available as a single unit or as a twin-pack (for higher, wider, heavier gates/ramps).
