LIFT OPENING REQUIREMENTS
(Cont)
:
OPENINGS IN SOLID WOOD JOISTS:
When ceiling joists are solid wood, the final opening size
must be
22½” x 46½”.
All side walls must be smooth and
perpendicular (the opening can’t be smaller at the
bottom). Cut sheet rock and decking flush with the walls.
Nothing can protrude inside the opening:
Nail heads
must be set flush or below the surface. Install the 2”x2” L-
flashing (provided) in the corners of the opening to cover
hanger brackets and nail heads (see Fig. 2a).
WARNING!: TO PREVENT LIFT
MALFUNCTION, THE OPENING
SIDEWALLS MUST BE SMOOTH
WITH NO PROTRUDING NAILS,
BRACKETS, SHEETROCK, ETC.
HOLE SIDE WALLS MUST
BE SMOOTH AND SQUARE.

INSTALL FLASHING IN ALL OPENINGS: Install the
2 x 2” L-flashing the corners of all openings,
even in
I-Joist openings that are paneled with 1/4” plywood.
Cut the flashing to the finished opening height (including
sheet rock and decking). Align it to the bottom and nail
both edges with #17 x 1” nails, placing nails within 1/4”
from each edge (Fig. 3). The flashing strips cover nail
heads and brackets while providing a slippery surface in
the opening to reduce paint wear on the lifting frame.

rock or decking must NOT protrude or extend into the opening, as this
can cause the lifting platform to hang up and malfunction, resulting in
possible damage or personal injury! Product warranty is void if the
opening does not meet the exact requirements detailed in these pages.

OPENINGS IN FABRICATED I-JOISTS:
When ceiling joists are “I-Joists” the rough opening size
must be 23 x 47” (½” larger in each dimension) to allow
space to panel the joists with 1/4” thick plywood (Fig.2b).
The 1/4” paneling will provide the required smooth walls
and cover I-joist ledges. The paneled final opening size
will then be 22½”x 46½”. The side walls must be square
(perpendicular) and all nail heads must be set flush or
below the surface. Cut all sheet rock and decking flush
with the edges of the opening. (See pgs. 8-9 on I-joists.)
Install the 2”x2” L-flashing (provided) in the corners of the
opening to cover hanger brackets & nail heads (Fig. 2b).

PILOT HOLES FOR MOUNTING THE LIFT:
Mark the
location of the mounting holes on the floor deck at either
end of the lift opening. These will be pilot holes for the
lag screws provided to secure the lift to the attic floor.
Find and mark the center on each side of the rectangular
opening, then use a straight edge or square to draw a
center line (Fig. 4). Next draw a line parallel to each of
the narrow ends and spaced 3/4” away from the opening.
Measure along the parallel lines 10” each way from the
center line and mark 4 hole centers (Fig. 4). Then
measure 2” over from the first 4 marks and mark 4 more
hole centers (Fig 4). Find the “Mounting Rails” in the
Versa Lift carton and place them over the hole centers
you have marked to check your work. The hole centers
should match the four slotted holes on the Mounting
Rails. If so, drill 8 pilot holes with a 5/32” bit on the hole
centers you have marked (Fig. 4). Approximate depth of
the pilot holes is 2-1/2”.
