5.7.3. The barrier is provided in the length needed for the platform side and should not
need to be trimmed. Insert 1-1/2” square threaded inserts into both ends of the 1-
1/2” x 2” barrier. Use a rubber mallet to fully seat the insert if needed (FIG. 5.21).
5.7.4. Assemble barrier attachment plates to barrier using a 5/16”-18 x 1” long hex bolts
and 5/16” flat washers. Note which side of the barrier the plates are attached to and
match the direction of ramp slope. If the upper end of the ramp or ramp run
terminates at a platform, use the “up sloping” plate. If the lower end of a ramp or
ramp run starts at a platform use the “down sloping” plate.
5.7.5. Note the orientation of the larger 3/8” diameter hole with respect to the 1-1/2” x 2”
section of the plate as shown (refer back to FIG. 5.3) to identify which barrier
attachment plate is needed.
5.7.6. Align the barrier attachment plates with sides of the barrier and tighten the fasteners
securely (FIG. 5.21).
