INSTALLATION INSTRUCTIONS
SP56-137 STANDARD PLATFORM LADDER
STEP 6:
Raise the ladder to the undercarriage (see Fig. 25) and insert the anchor bolts one at a time (see
Fig. 26). The anchors should run parallel with the length of the tube so that when the bolt is turned the nut
will be held in place by the sides of the tube. Be sure the anchor nut does not pinch any wires or cables that
may be in the tube. It is helpful to apply some light downward pressure as you tighten the bolts to prevent
the anchors from turning. Do not tighten one corner completely before proceeding to the next. Rather, loosely
screw in one corner, then the next. Repeat until all corners are snug, then fasten tightly (see Fig. 27). DO NOT
OVER TIGHTEN!
NOTE:
If the anchor nut does not disengage on its own, a longer bolt may need to be used.
STEP 7:
Add Tek screws in several places to secure the frame to the 5th wheel, catching as many additional
support tubes as possible (see Fig. 28). If the predrilled holes in the ladder frame mount do not match up with
the markings for the crossmembers, new holes may need to be drilled in the ladder frame mount to match
additional structural locations.
STEP 8:
Insert the ladder & platform from the fire escape window side of the unit, platform first (see Fig.
29). Once the platform is inserted into the frame mount, tighten the ladder stops with 1/4”-20 carriage bolts
and nylock nuts that are provided (see Fig. 30). The ladder is now installed, but the front of the ladder must be
locked for safe travel (see Fig. 31 on following page and Owner’s Manual).
