Successfully constructing a wood fence with steel end posts includes securing the posts to the wooden railings. Doing so enhances your fence's structural support and extends its overall life. This end post adapter has been designed and fabricated to accommodate 3" metal posts, featuring a hooked edge to grip onto a horizontal rail, with numerous screw holes for attachment. The looped piece through which the post's inserted likewise features a screwed accessor, allowing you to clamp the post in place. This adapter has been fabricated using galvanized steel, which yields excellent rust resistance: a must-have quality for all fence parts, as they're perpetually exposed to the elements. Don't settle for a fence part that'll rust and break apart after several years of rain!
