PRO SERIES INSTALLATION GUIDE
ROOF HOOK CAPACITIES AND ENGINEERING
Refer to engineering report tables for tested allowable loads. Refer to local AHJ to determine
the correct code (ASCE 7-05, 7-10 or 7-16) and environmental loads. It is the responsibility of
the installer to ensure these mounting attachments are appropriate for the application. Please
contact your 3
rd
party engineer for more information.
ENGINEERING GUIDE LIMITATIONS
• Flush roof installations only
• Roof slope must be 0-45 degrees (0/12 - 12/12 pitch)
• Surrounding ground area must not slope more than 10 degrees
• Location must fall into Exposure Category B or C
Please refer to the Solarmount Installation Manual for proper installation of the Solarmount
system. SOLARHOOKS are intended to replace L-feet in the system and the rail connection
should be torqued to the appropriate Lfoot to rail torque specification from the Solarmount
manual.
Please refer to www.unirac.com in the Technical Support section for the Solarmount D&E guide
which should be used in installations that do not comply with the limitations above.
Follow all local and OSHA safety guidelines when installing.
GETTING STARTED
NOTES:
(1) Thread must be embedded in the side grain of a rafter or other structural member integral
with the building structure.
(2) Lag bolts must be located in the middle third of the structural member.
(3) This table does not include shear capacities. If necessary, contact a local engineer to specify
lag bolt size with regard to shear forces.
(4) Install lag bolts with head and washer flush to surface (no gap). Do not over torque.
(5) Withdrawal design values for lag screw connections shall be multiplied by applicable
adjustment factors if necessary. See table 10.3 in the American Wood Council NDS for Wood
Construction
FIGURE 1 AND ASSOCIATED NOTES (for reference only)
Refer to latest AWC, NDS data to select a lag bolt embedment depth to satisfy your Uplift Point
Load Force (lbs), requirements. It is the installer’s responsibility to verify that the substructure
and attachment method is strong enough to support the maximum point loads calculated.
