UNIRAC FlashLoc Duo Installation Guide

UNIRAC FlashLoc Duo

THE MOST VERSATILE DIRECT TO DECK ATTACHMENT
FLASHLOC™ DUO is the most versatile direct to deck and rafter attachment for composition shingle and rolled comp roofs. The all-in-one mount installs fast — no kneeling on hot roofs to install flashing, no prying or cutting shingles, no pulling nails. Simply drive the required number of screws to secure the mount and inject sealant into the base. FLASHLOC’s patented TRIPLE SEAL technology preserves the roof and protects the penetration with a permanent pressure seal. Kitted with two rafter screws, sealant and hardware for maximum convenience (deck screws sold separately). Don’t just divert water, LOC it out!

PRE-INSTALL

CLEAN SURFACE AND MARK LOCATION
Ensure existing roof structure is capable of supporting the roof attachment point loads stated in the racking system engineering specifications. Clean roof surface of dirt, debris, snow and ice.
Snap chalk lines for attachment rows. On shingle roofs, snap lines 1/4” belo w upslope edge of shingle coarse. This line will be used to align the upper edge of the mount.
NOTE: Space mounts per racking system installation specifications.

STEP ONE: SECURE

• ATTACHING TO A RAFTER: Place FLASHLOC DUO over rafter location with sealant port on up-slope side and align upper edge of mount with horizontal chalk line. Secure mount with the two (2) provided rafter screws. BACKFILL ALL PILOT HOLES WITH SEALANT.
• ATTACHING TO SHEATHING: Place FLASHLOC DUO over desired location with sealant port on up-slope side and align upper edge of mount with horizontal chalk line. Secure mount with the two (2) provided rafter screws. Next, secure mount with four (4) deck screws by drilling through the FLASHLOC DUO deck mount hole locations. Unirac recommends using a drill as opposed to an impact gun to prevent over-tightening or stripping roof sheathing.
• IMPORTANT: SECURELY ATTACH MOUNT BUT DO NOT OVERTIGHTEN SCREWS.

STEP TWO: SEAL

• Insert tip of UNIRAC approved sealant into port and inject until sealant exits vent. Follow sealant manufacturer’s instructions. Follow sealant manufacturer’s cold weather application guidelines, if applicable.
• NOTE: When FLASHLOC DUO is installed over gap between shingle tabs or vertical joints, fill gap/joint with sealant between mount and upslope edge of shingle course.
• CUT SHINGLES AS REQUIRED: DO NOT INSTALL THE FLASHLOC SLIDER ACCROSS THICKNESS
• VARIATIONS GREATER THAN 1/8″ SUCH AS THOSE FOUND IN HIGH DEFINITION SHINGLES.
• NOTE: If an exploratory hole falls outside of the area covered by the sealant, flash hole accordingly. NOTE: Read and comply with the Flashloc Duo Design & Engineering Guide prior to design and installation of the system.
• USE ONLY UNIRAC APPROVED SEALANTS. PLEASE CONTACT UNIRAC FOR FULL LIST OF COMPATIBLE SEALANTS.
• Continue array installation. Refer to SOLARMOUNT or NXT HORIZON Installation Guide for the remaining system installation.
