4.2. STARTER FRAME
4.2.1. The starter ramp (identifiable by its tapered section for transition to the ground) includes
starter frames which are specific to the starter ramp, lower post supports, and 6’
handrails. The procedure for attaching starter frames is the same for both two-line rails
and picketed guards.
4.2.2. One starter frame is required on each side of the ramp but are interchangeable side-to-
side. The shorter starter frame post is the lower post.
4.2.3. Connect the starter frame top rails and upper frame post to the ramp in the same
manner described in the previous section.
4.2.4. Refer to FIGs. 4.3 and 4.4 and the following steps when installing the lower frame post
supports:
4.2.4.1. Lower frame post supports are left or right hand (looking up the ramp from
the start).
4.2.4.2. Install a lower frame post support on both starter frame lower posts. Orient
the set screws in the pocket of the lower frame post support facing outward
and toward the start of the ramp (FIG. 4.4).
4.2.4.3. Loosen the set screws in the pocket of the lower frame post support, if
needed, to fully engage the lower posts in the post support.
4.3. ANCHORING FRAMES AND CODE COMPLIANCY: If a code compliant system is needed, the lower frame
post supports must be anchored to the ground.
4.3.1. Drill four holes in each lower frame post support base (FIG. 4.3), then install four 1/4” or
3/8” x 2-1/2” (minimum) concrete anchors (supplied by others) per lower post support. It
is the installer’s responsibility to ensure the intended mounting surface is of sufficient
strength and quality to hold the anchors used.
4.3.2. Use the holes lower frame post support base as a template to mark and drill holes for the
anchors.
You may wish to remove the lower frame before drilling anchor
holes, then reinstall when anchor hole drilling is complete.
Always install concrete anchors per the manufacture’s
recommendations.
If attaching to a surface other than concrete, consult your
structural engineer or the factory for alternate anchoring
methods.
4.3.3. Attach the lower frame post supports to the ramp side rails using the supplied 5/16”-18 x
3” square neck carriage bolts, 5/16”-18 nylon insert locknuts, and 5/16” flat washers.
Ensure that the head of the carriage bolts are on the ramp side as shown (FIG. 4.4).
If the holes in the lower frame post support do not align with the
holes in the lower frame post and ramp side rail, the lower frame
post support is most likely installed on the wrong side of the ramp.
4.3.4. Tighten all fasteners securely, including the 3/8”-16 headless socket set screws in the
pockets of the lower frame post supports.
4.3.5. The procedure for ramp handrail installation is the same for the starter ramp as other
standard ramps; see SECTION 4.3.
