Method #2
Module Layout
•
Lay the modules face-down on a flat surface (plywood on sawhorses, shop floor, large
workbench, etc.) as they will be configured on the rack.
•
Leave at least 1/4” space between adjacent module edges.
•
The outside to outside distance of the module array must be 115” or less. This is
necessary to allow at least 2” between the canister and the outside edge of the
module.
•
Pre-install the required number of 1/4” hex bolts in the extruded rail. Make sure to use
the correct slot and check to be sure that the bearing cutout faces towards the inside of
the rack and is offset towards the module (see drawing).
•
Carefully arrange the 1/4” bolts so they line up with the module holes.
•
Install the Cross Arm on to the row of modules. Install provided flange nuts. Hand
tighten only.
•
Repeat this process with the other Cross Arm.
•
Check alignment.
•
Tighten the flange nuts to no more than 75 in-lbs (6 ft-lbs).
Bearing Installation
•
Install bearings as shown. Note the
mounting side of the bearings faces
outwards.
•
While holding the square welded nuts
with either a 1” open-end wrench or
adjustable wrench, tighten 5/8” bolts to
approximately 40-50 ft-lbs.
•
The bearings are designed to swivel
and may not look “square” with respect
to the axle.
