Liberty Series™ Ramp Installation Guide-Revision 8/1/2020
Legs should not be placed directly on a soft surface, such as dirt, grass, or loose gravel, as the legs
could sink over time; instead, place legs on cement paver stones, available in hardware stores, or
National Ramp Celebration Footer Pads
TM
. When a Footer Pad is being used on a soft surface, it
should be installed with the ribbed side on the ground.
The Footer Pads should not be used on hard surfaces, such as concrete and pavement, as they can
easily be knocked out of place, causing the ramp to be unsteady. When faced with a surface such
as gravel or cracked concrete, try to first place the leg on the Footer Pad, and then give the Footer
Pad a tap with your foot. If it easily slides out of place, remove it and place the leg directly on the
ground. If it stays in place, keep it, with the ribbed side facing up.
When a leg is going to rest on a Footer Pad or paver stone, the leg height will be measured to the
Footer Pad, and not to the ground.
