TREX® Adjustable Foot Block for Composite Railing – Mid-Span Support for Stronger, Straighter Railings
The TREX® Adjustable Foot Block is designed to provide critical mid-span support for composite bottom rails in the TREX Transcend®, Select®, and Enhance® railing systems. This foot block helps prevent rail sagging over time—especially on longer runs—while adjusting to fit varying rail heights and surfaces for a secure, level, and code-compliant installation.
Key Features:
✔ Adjustable Height – Easily extends or contracts to fit the required gap between the deck surface and the bottom rail, offering flexibility for different deck slopes and railing heights.
✔ Prevents Sagging – Adds essential support to the bottom rail in the center of 6’ or 8’ spans, maintaining structural integrity and visual alignment over time.
✔ Durable, Weather-Resistant Construction – Made from high-strength polymer for long-term performance and resistance to moisture, UV rays, and temperature changes.
✔ Compatible with TREX Composite Railing – Designed to work with TREX Transcend®, Enhance®, and Select® bottom rails.
✔ Easy to Install – Snaps into place under the bottom rail or mounts with included fasteners; adjustable to the desired height without tools.
✔ Low-Profile Design – Discreet look that blends seamlessly under the rail for a clean, finished appearance.
