Frequently Asked Questions

What type of decking is the EB14W compatible with?

The EB14W biscuit is designed for use with 3/4-in. or greater kiln-dried decking that has a moisture content less than air dry, which is approximately 19%. This ensures proper fit, secure holding, and accommodates natural seasonal wood movement.

What board spacing does this hidden deck fastener system provide?

The EB-TY EB14W system is engineered to maintain a consistent 1/4-in. spacing between deck boards. The underside keel on each biscuit helps ensure accurate and uniform fastener positioning across every installation.

How does the EB-GUIDE predrilling tool improve installation?

The patented EB-GUIDE predrilling tool is included in this kit and provides precise fastener angle alignment for consistent biscuit installations. When used with the included 1/8-in. quick-release impact-ready drill bit, it simplifies the process and helps ensure repeatable, professional results across every board.

Why do the screws in this kit have black-painted heads?

The Type 305 stainless-steel trim-head, 6-lobe screws are finished with black-painted heads specifically to blend in visually with the EB-TY biscuit. This detail supports the system's hidden fastening aesthetic, keeping the finished deck surface clean and free of visible hardware.
