Unirac FlashLoc Duo Dark, 004275D (20 pack)

The Unirac 004275D FlashLoc Duo Dark is a versatile, all-in-one pitched roof attachment solution optimized for composition shingle and rolled composition roofs. As an advanced member of the FlashLoc® family, the FlashLoc Duo stands out with its dual-mounting capability—securing directly to either the roof deck (e.g., OSB or plywood) or rafters—while delivering fast, watertight performance without traditional flashing. This makes it the most flexible and installer-friendly option for comp shingle solar PV systems.

Key Features

Dual Mounting Flexibility: Engineered for both deck and rafter attachments, eliminating the need to locate rafters precisely in every scenario and providing greater placement options on various roof structures.
Patented TRIPLE SEAL Technology: Combines an outer shield contour-conforming gasket, pressurized sealant, and additional sealing elements to create a permanent, watertight barrier that protects the roof penetration and prevents leaks effectively.
Dark Finish: Sleek dark (anodized black/dark bronze) aesthetic that integrates seamlessly with darker shingles and modern residential/commercial designs for a clean, professional appearance.
Complete All-in-One Kit: Each unit includes:

FlashLoc Duo attachment base with integrated pressure seal and gasket
Stainless steel lag bolt (typically 5/16″ x appropriate length for deck/rafter penetration) with EPDM sealing washer
3/8″-16 x 1″ bonded T-bolt and serrated flange nut for secure rail connection
Often pre-packaged with sealant where required

Ultra-Fast, Low-Impact Installation: Simple process—position the attachment, drive the lag bolt into the deck or rafter, and secure to the rail. No kneeling to install flashing, no prying/cutting shingles, no pulling nails—reducing roof disturbance, labor time, and heat exposure on hot days.
Durability and Compliance: High-strength aluminum construction with rigorous engineering per ASCE 7 standards (including 7-10, 7-16, and 7-22). Supports full system certifications (e.g., UL 2703 when paired with Unirac rails like NXT or SolarMount), component testing, and high wind/weather resistance.

Benefits
The FlashLoc Duo Dark streamlines installations by offering unmatched versatility—ideal for roofs with inconsistent rafter spacing or mixed decking—while prioritizing roof preservation and speed. Its no-flash design minimizes material handling and job-site complexity, often sold in efficient 20-packs (though available per unit). Backed by Unirac’s reputation for quality, it pairs excellently with systems like NXT Umount® or SolarMount®, contributing to 25-year warranties in compatible configurations.
This positions the Unirac 004275D FlashLoc Duo Dark as the go-to choice for solar professionals needing a reliable, aesthetically superior, and highly adaptable attachment for composition roofs.
