Trex Transcend® Birdsmouth Gasket Pack in 45°
TREX Transcend® Birdsmouth Gasket Pack – 45° – Clean, Sealed Finish for Angled Stair Railing Installations
The TREX Transcend® Birdsmouth Gasket Pack in 45° is designed to provide a precise, finished seal at the connection point between stair rails and post sleeves where the rail meets at a 45° angle. These gaskets help conceal gaps, improve the appearance of angled cuts, and block out debris and moisture—essential for both durability and a polished look in your stair railing system.
Key Features:
✔ Made for 45° Stair Angles – Specifically engineered to fit between the stair rail and post sleeve at a 45° angle, typically used in standard stair applications.
✔ Provides a Clean, Professional Finish – Fills in gaps at stair rail-to-post connections for a smoother transition and a more finished appearance.
✔ Seals and Protects – Helps prevent water, dirt, and debris from entering exposed cuts or bracket areas, extending the life of your railing.
✔ Color-Matched Options – Available in TREX Transcend® railing colours such as Classic White, Vintage Lantern, Gravel Path, and more to blend with your system.
✔ Durable, Weather-Resistant Material – Made from long-lasting composite or rubber-like material that resists UV damage, cracking, and shrinkage.
✔ Easy Installation – Slides into place between the stair rail and post sleeve during bracket installation—no special tools required.
