Installation is easy - everything takes place on the top-side. First, use a biscuit joiner to cut slots in each deck board where it crosses a joist. Then, apply a thin bead of construction adhesive to the top of the joists. Next, drive a #7 x 2-1/4" long stainless steel trim head screw through the Eb-Ty clip and decking board and into the joist at a 45 degree angle (there isn't any need to measure, the clips automatically set the angle). Eb-Ty hidden deck fasteners' unique design locks everything together like the tongue and groove of a hardwood floor. (Download Eb-Ty Installation Instructions)

Original Eb-Ty hidden deck fasteners work best with dimensionally stable decking materials such as tropical hardwoods from 3/4" to 5/4" thick. Eb-Ty "Live Cylinder" fasteners provide 1/4" spacing to accommodate the seasonal expansion and contraction of composite materials such as Trex® or standard pressure treated materials. Finally, Eb-Ty “BIG” fasteners are designed for use with 2 x 4’s and 2 x 6’s, so they're 5/8" tall and provide a 1/4" gap between boards, and penetrate deeper into the decking to provide for the inevitable shrinking and swelling of pressure treated decking.

Eb-Ty hidden deck fasteners received the 1998 Construction Innovation Award from the editors of The Journal of Light Construction, have been reviewed in a number of national publications, including Fine Homebuilding (March 1998), and appeared on The Learning Channel show “Men in Tool Belts”. Made in the USA of UV resistant polypropylene.
