To install the Ladders and the Top Cap:
1. Take a Ladder and slide it down the back of a Post, with the Bolt Hole end at the bottom.
Make sure the Ladder goes through
both Slots on each Gusset. There is a Slot at the top of the
Gusset and another Slot at the bottom of the Gusset; both are formed by the Slide Blocks.
Important: It is easy to see the top Slot created by the Slide Blocks. It is difficult to see the
bottom Slot, but it is
required that the Ladder go through both Slots.
If the Ladder misses a Slot or the Slide Blocks were not installed correctly, your Safety Locks will
not function correctly.
⚠ WARNING Make sure all four Ladders go through both Slots created by the Slide Blocks.
2. Install the other three Ladders the same way.
3.
Moving to the top of the Ladders , move the Stop Nut half of the way down towards the top
of the Ladder.
4. Put a Top Cap onto the top of the Post: put the Threaded Bolt on the top of the Ladder through
the appropriate hole, put the tabs on the side of the Top Cap inside the Post, and secure the Top
Cap on both sides with one Hex Head Bolt and one Nyloc Nut per side.
5. Once the Top Cap is secure, move the Stop Nut up until it contacts the underside of the Top Cap,
then add a Flat Washer and Nyloc Nut to the top of the Top Cap and tighten. Hand tighten only.
You are looking for about an inch of thread above the top of the Top Nut.
Note: The other hole in the middle of the Top Cap is for the Lifting Cable, installed later.
6. Install the other three Top Caps the same way.
