ShadowDeck™ T-Shaped Fastener

The Perfect Boundary Board Connection

The ShadowDeck™ T-Shaped Fastener is the purpose-built solution for joining your boundary board to the ends of your decking boards — delivering a clean, seamless perimeter finish that looks as good as it performs.

Engineered specifically for the ShadowDeck™ hidden fastener system, the T-shaped profile locates your picture frame or boundary board at precisely the correct height relative to your decking board ends, ensuring a flush, professional result every time.

Key Features

• Designed for boundary board connections — joins the perimeter board to the butt ends of your decking boards with precision
• T-shaped profile — locates the boundary board at the exact correct height for a flush, level finish
• Hidden fastening — keeps the deck surface nail-free and visually clean
• Works with the ShadowDeck™ system — designed to integrate seamlessly with the full range of ShadowDeck™ fasteners and pre-grooved timber
• DIY-friendly — straightforward to install, with no specialist tools required

How It Works

The T-Shaped Fastener slots into the groove of your decking board ends and holds the boundary board firmly in place at the right height. A second joist positioned 45mm out from the boundary joist accommodates a standard 3mm fastener for the next board run. Refer to our Installation Guide for full picture framing instructions.
