Mayline Four Post Shelving - Manual (Page 7)

UPPER AND LOWER SPREADERS: When
specifying roll out drawers you will use two
lower spreaders and two upper spreaders for
each 4-Post unit. The lower spreader will
replace the lower shelf support, its additional
height will help to stabilize the unit. The upper
spreader would replace a shelf support in the
area above the top drawer, again the additional
height will help to stabilize the unit. Both upper
and lower spreaders are installed the same as
our standard shelf support. Place the tabs in
the holes in uprights and use a rubber mallet to
seat in place.
Rollout Drawer Assembly / Installation
When attaching shelving to the floor
use (4) 1/4" masonry wedge anchors
for concrete or (4) 1/4" wood screws
when going into another material.
Not recommended for mounting on a
carpeted floor.
