Ramps are sloped pathways that provide access between two levels. BoltHold anchors are often used when at least one end of the ramp is resting on asphalt. A common application is when the ramp high level is attached to the building structure, and the lower level is in a parking lot.
If the high level is firmly attached to the building concrete structure, use SP10 anchors for the lower level anchoring. If the ramp is free-standing and supported by 4 or more posts, all of which are on asphalt, use the SP12 for a heavy (>300 lbs.) ramp and SP18 for a light weight ramp.
