Our patent-pending products are designed specifically with the recreational vehicle owner in mind. They feature a non-marring, clamp on design that allows for semi-permanent mounting to the rails of most rear-facing recreational vehicle roof access ladders – with absolutely no permanent alterations being made to the vehicle itself!
Standard dimensions for roof access ladder rails are 1” outside diameter tubing on 11” centers. We have found that in application there is actually some variation across recreational vehicle makes and models and have adapted our design accordingly. Our products will readily mount to rails constructed of 1” OD tubing or 1” square tubing, having center to center dimensions from 11” to 11.5”. These are critical dimensions – please verify your application meets these specifications prior to placing your order.
