Frame: The vertical uprights and the top and bottom
cross bracing are 2" x 1" x 1/8" thick extruded aluminum channels,
welded to form a rigid frame. Each vertical upright is fabricated with a
series of obtuse angle slots, 1-5/8" on centers, to receive and contain
the guides. Caster support channels are 1-7/8" x 4" x 1/8" thick
extruded aluminum, fully welded to the vertical uprights and bottom
Guides:The two level guides are 1/2" x 1" x 7/8" x
3-1/8" x .105" thick extruded aluminum, with all corners chamfered and
deburred. They are easily removable and are securely held in position by
a series of obtuse angle slots, 1-5/8” on center, which are punched in
one wall of each channel upright.
Rod:All models have 1/2" diameter aluminum tie rods
welded to the front and rear vertical uprights for extra rigidity
Casters:The units are mounted on four 5" diameter,
heavy duty, swivel casters.
