LIFT OPENING SPECIFICATIONS
(Cont)
:
OPENINGS IN SOLID WOOD JOISTS:
For solid wood joists, 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 sur-
face. Install the 2”x2” L-flashing in the corners of the open-
ing to cover hanger brackets and nail heads (see Fig. 2a).
LIFT OPENING WITH SOLID WOOD JOISTS
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.

OPENINGS IN FABRICATED I-JOISTS:
For “I-Joists” make a rough opening of 23 x 47” and panel
all four sides with 1/4” thick plywood (Fig.2b). The final
opening size with paneling will be 22½”x 46½” . The panels
provide the required smooth walls and cover I-joist ledges.
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.
Install the 2”x2” L-flashing (provided) in the corners of the
opening to cover hanger brackets & nail heads (Fig. 2b). For
more information on framing for I-joists, see pgs. 8 and 9.

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”.

WARNING
THE VERSA LIFT OPENING MUST HAVE
SMOOTH PERPENDICULAR SIDE WALLS: Nail heads,
hanger brackets, sheet rock or decking must NOT pro-
trude 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.
