The HSR or High Side Rail adapter hole-mount style is ideal for use on lifts where the adapters are the drop-in kind that can easily be lifted out. Once the standard lift adapter bases are removed and replaced with the optional height extensions, the side rail supports can be easily put in their place for full arm support. After installing the side rails simply set each lifting tray over the rails in the desired position and go. HSR style turf and utility vehicle tray attachments for two-post surface mount lifts are perfect for just about any suitable application found at golf courses, airports, ATV dealers, city, state and municipal parks, college campuses and so many other locations that have two-post surface-mount lifts and need a broader range of lifting capabilities.
