Position the female stair connector on the step flange, making sure it is level and meets the top of the pool panel.
Hold in place with vise grips or C-clamps. Using a 7/16” drill bit, drill through the step flange at the holes in the
female stair connector. Bolt the adapter plate on to the step flange using the backer washer and nut on the inside of
the step flange. Attach the male stair connector to the female stair connector at the ball joint.
Important: Keep nuts very loose until all panels are installed.
T-spline assembly / Final adjusting
The extended T-spline is installed on the exterior side of the pool, with holes to attach the the A-frame components.
The 10” standard spline is installed on top of the T-spline. The 52” standard spline is installed on the interior side of
the round pool.
Final adjusting of the step is done after all the panels are
installed and stair adapter kit nuts are tightened. Check
panel joints and step ends for proper location –using
the radius of the pool from the established center
point of the pool.
Encase the base of the pool and step with a
concrete collar. See concrete requirements
on page 21.
