Unirac SHBUTYLD2 Stronghold Dark Attachment Kit
Unirac Stronghold Dark Attachment Kit SHBUTYLD2
The STRONGHOLD™ Butyl (SHBUTYLD2) is a direct-to-deck/rafter roof attachment with a pre-applied butyl pad for fast, flashless installs. Just peel the liner, place the mount, and drive the included screws—the butyl conforms around fasteners and shingle granules to create a robust, watertight seal. It’s optimized to pair with Unirac’s NXT UMOUNT™ rail system and ships with an NXT rail clamp for a clean, integrated install.
