STEP 4: Continued
Another transfer method uses a Self Leveling Laser Alignment Tool. CRL's PLS3 works extremely well for transferring
the marks from floor to ceiling with an accuracy of 1/4" per 100' .Given the amount of unsuitability built into the support
system, the PLS3 is well within tolerance. The tool also self-levels to any floor that is within 6˚ of horizontal. Switch the
laser on and place the downward beam directly
over the cross mark of the center bracket
hole. For this application it does not matter
which way the device is pointing as we are only
concerned with the overhead indicator dot for
our ceiling holes. Mark each bracket center hole
location on the ceiling surface.
STEP 5 Bracket Attachment. Typically the brackets are attached to a steel structure like an I-Beam or Channel, a Concrete
Ceiling, or a Laminated Beam.
Recommended hanger spacing: Parking Area: Min 18" on center
Lock washers should be used at all nut locations. The ceiling support structure design should be capable of
supporting a concentrated dead load of 1,135 lbs at each anchor point.
Continue attaching all the system Dual Rod Brackets before proceeding to the next step. Be sure to properly orient
each one before tightening the fasteners.
