5. Align the holes of a triangular mounting bracket with

the holes on a respective handle section. Place a #10-

24x1-1/2" bolt through each set of holes and fasten each

with a #10-24 nut with nylon lock insert. Tighten the bolt

to 16-18 in-lbs until snug to surface (see Diagram #5).

Be careful not to over-tighten the bolt or tube may be

crushed. Repeat with the other handle section.

6. The ladder as packaged is designed with lower mount

pads that are intended to mount to the rear wall

approximately 78" below the roof line. With the ladder

handles resting on the roof, it can be determined if the

ladder will need to be modified to align with any backer

location(s).

If there is an intended backer location that the ladder

must be shortened in order to align to, measure the

distance from the backer location to the center of the

mounting pad. NOTE: 3" of straight tube section must

remain on the handle to properly attach to the Upper

Ladder Section; total removed material section cannot

exceed 3". Once this distance has been determined,

remove the ladder from the roof and disassemble both

the handle portions from the upper ladder assembly by

removing the #10-24x1-1/2" bolt and #10-24 nut with

nylon lock insert. Mark the measured distance on the

handle portion from the end that the upper ladder

assembly inserts into. Using a hacksaw or tube cutter,

remove the end of the handle portion at the mark. Slide

the handle sections over the smaller-diameter inserts of

the upper ladder section. Turn the handles until they are

perpendicular to the ladder section and drill a 13/64"

hole through each handle and inner tube insert

approximately 1-1/2" from the handle insert end (see

Diagram #6). Replace the #10-24x1-1/2" bolt through

each set of holes and fasten each with a #10-24 nut with

nylon lock insert. Tighten the bolt to 16-18 in-lb until

snug to surface (see Diagram #7). Be careful not to

over-tighten the bolt or tube may be crushed. Set the

ladder back into position with its handles resting on the

roof.
