Center object under mounting points. Position
mounting boards far enough apart so object is stable.
STEP 1 CONTINUED: DETERMINE HOISTER LOCATION
WARNING! Do not screw into laminated rafters.
They are not intended to accept fasteners. Consult
rafter maker for recommendations. Screwing
into laminated rafters may considerably weaken
system, causing load to fall which may cause
an accident.

B. PLAN LOCATION OF MOUNTING BOARDS
Mounting boards are used to position Hoister directly
above object to be lifted.
Note:
Mounting boards may not be necessary for
nstallation in ceiling with exposed rafters. In ceilings
with exposed rafters, system can be installed on rafters.
Position Hoister directly above object to be lifted. If
installing without mounting boards, go to step 3.
DISTANCE BETWEEN MOUNTING BOARDS
Distance between mounting boards should be 1/3 of
object’s length.
Exception:
Distance between mounting boards for long
SUPs will be less than 1/3 object’s length.
Calculate distance between mounting boards using
formula or chart below.
