Wood Post Lag System
The Hayn Wood Post Lag System is a Traditional Cable Rail tensioning assembly that combines a lag screw mount with a swage wire terminal and turnbuckle body, providing direct wood post attachment without requiring a through-hole or backing plate, available in machine swage, Hayn Grip, and Handy Crimp configurations for wire sizes from 1/8" through 1/4".
Wood Post Lag System
The lag screw end drives directly into the wood post, eliminating the need to drill a clearance hole and fit a bolt and nut on the far side — which makes this the most installer-friendly Traditional cable rail termination option for wood-framed structures. The system requires a minimum of 3" of solid wood blocking behind the mounting surface for full thread engagement, and the strength of the assembly is limited by the lag holding power of the mounting material rather than the cable hardware itself, so solid blocking is not optional. Available in five machine swage configurations and additional Hayn Grip and Handy Crimp options covering thread sizes from 1/4-28 through 5/16-24 and wire sizes from 1/8" through 1/4", with a 3" to 3-1/4" adjustment range and a 50-foot maximum run length per span.
