Side / Guide Installation
Adjustable Guides
uInstalling Adjustable Guide Brackets
For guides used with Top Drive Mounting Packages, Guiderail may need to be installed 3” down conveyor, as there will be interference between Guiderail and Drive Mounting
Plate; this will cause guides to extend 3” beyond end of conveyor.

apart, evenly spaced using 7/8”
thread forming torx head screws.
