joists.
The front and back joists are the shorter ones with
the notch facing upwards.

and secure with 1 ½” (38mm) screws at both ends of
each joist.
Ensure the middle joists are flush to the front and
back joists and secure them together with 1 ½”
(38mm) screws in the pre drilled holes.
Repeat for all 4 corners.
