7.2. RAMP LOWER TRANSITION
7.2.1. The lower transition, in combination with a PRST (RAMP SUPPORT TOP), is commonly
used to span wider gaps or accommodate larger angular misalignment than can be
achieved with an upper transition. It can also be used in place of the ground transition in
some situations. Despite being called a lower transition, it can be used at either end of a
ramp or ramp run.
The lower transition is the larger of the two transitions.
7.2.2. Lift the end of the ramp and install the lower transition as shown (FIG. 7.3).
7.2.3. If the lower transition is resting on the ground, anchoring is optional.
7.2.4. If a lower transition is resting on any type of raised area (i.e., a platform, deck, or porch), it
must be anchored using the same procedures as used in ‘ANCHOR RAMP UPPER TRANSITION’.
7.3. SINGLE BRIDGE PLATE
7.3.1. Securing to WOOD SURFACE OR PLATFORM:
7.3.1.1. To secure to a wooden deck or platform, use the four supplied 1/4” x 1” self-drilling
self-tapping screws.
7.3.2. Securing to CONCRETE:
7.3.2.1. To secure to concrete, drill a 1/4” diameter hole at least 1-1/4” deep. Ensure that
all debris from the hole is removed using a shop vacuum, blower, or another
suitable type of equipment.
7.3.2.2. Insert the four supplied pin head mushroom anchors and secure by using a hammer
to drive the pin in flush with the mushroom.
Use PBPxx (BRIDGE PLATE) in the horizontal (flat) position only.
It is intended to be used to bridge gaps up to a maximum of 6” between a platform and a porch
or deck. IT IS NOT INTENDED TO BE USED AS A RAMP OR ON AN INCLINE.
Ensure that at least 1” on each of the supporting edges of the plate is supported on a good,
sound construction surface that is free from defects (FIG. 7.4).
