The Hampton Products-Wright V591 is a 42-inch zinc-plated turnbuckle designed to correct out-of-square narrow wooden or vinyl doors. The unit installs diagonally across the door face, and the center dial rotates to draw the two halves together, applying tension that pulls the door frame back into alignment. At 1.8 pounds, the hardware is lightweight enough for single-person installation. The zinc plating provides corrosion resistance suited to exterior door applications exposed to weather and humidity. This is a hardware-trade and general contractor staple for door remediation work on residential and light commercial properties.
This turnbuckle is intended for narrow wooden and vinyl doors that have racked or fallen out of square over time, a common condition in older residential construction or in structures subject to settling. It mounts diagonally on the door surface, spanning from one corner to the opposing corner, and the adjustable center mechanism allows the installer to fine-tune tension until the door closes and latches correctly. The package includes 5 units, making it practical for multi-door service calls or tract housing work.
Designed for use on narrow wooden and vinyl doors that are out of square. Attaches diagonally to the door face for racking correction.
Installation is typically performed by a general contractor, finish carpenter, or experienced handyman. Attach one end of the turnbuckle at the top corner of the door on the hinge side and the opposite end at the bottom corner on the latch side, or reverse the orientation depending on the direction of rack. Rotate the center dial gradually to apply tension evenly rather than advancing it all at once. Ensure all existing door hardware and hinges are properly fastened before installing the turnbuckle to avoid compounding alignment issues.
