FLASH LOC
INSTALLATION GUIDE
STEP 1: SECURE
Place FLASHLOC over pilot hole with lag on down-slope side. Align indicator marks on sides of
mount with chalk line. Pass included lag bolt and sealing washer through FLASHLOC into pilot
hole. Drive lag bolt until mount is held firmly in place.
NOTE: The EPDM in the sealing washer will expand beyond the edge of the metal washer when
proper torque is applied.
PRE-INSTALL
Snap chalk lines for attachment rows. On shingle roofs, snap lines 1-3/4” below upslope edge
of shingle course. Locate rafters and mark attachment locations.
At each location, drill a 7/32” pilot hole. Clean roof surface of dirt, debris, snow, and ice.
Next, BACKFILL ALL PILOT HOLES WITH SEALANT.
NOTE: Space mounts per racking system install specifications.
STEP 2: SEAL
Insert tip of UNIRAC provided sealant into port. Inject until sealant exits both vents.
Continue array installation, attaching rails to mounts with provided T-bolts.
NOTE: When FLASHLOC is installed over gap between shingle tabs or vertical joints,
fill gap/joint with sealant between mount and upslope edge of shingle course.
USE ONLY UNIRAC APPROVED SEALANTS: Chemlink Duralink 50 (included in kit) or Chemlink M-1
