3.7. ANGLE RAMPS WITH RESPECT TO PLATFORMS, PORCHES, OR DECKS
There are situations where it is necessary to angle ramps with respect to a platform, porch or deck.
The components required are not normally included with a typical system unless it is a ramp or ramp
run without a platform. If a ramp must be angled when attaching to a platform, a PRUT (RAMP UPPER
TRANSITION) or PRLT (RAMP LOWER TRANSITION) with a PRST (RAMP SUPPORT TOP) must be used
instead of a PRHP (RAMP HANGER PAIR). The same components can be used at the top and bottom of
ramp or ramp runs depending on the angle required.
3.7.1. Angles up to approximately 3° can be accommodated using the PRUT (RAMP UPPER
TRANSITION) as long as the PRUT (RAMP UPPER TRANSITION) overlaps the surface of the
platform, porch or deck by at least 1” (FIG. 3.17).
3.7.2. Angles up to approximately 6° can be accommodated using the PRLT (RAMP LOWER
TRANSITION) with a PRST (RAMP SUPPORT TOP) and ramp legs. Legs must be used on
both sides of the ramp when angled over 3°. Refer to the appropriate sections in
‘OPTIONAL EQUIPMENT’ for installing the PRUT (RAMP UPPER TRANSITION) or PRLT
(RAMP LOWER TRANSITION) (FIG. 3.18).
3.7.3. The PRLT (RAMP LOWER TRANSITION) should overlap the surface of the platform, porch
or deck by at least 1” regardless of the angle required (FIG. 3.18).
