Adjustable device for correcting door warp - has braces extending from lock plate to anchor blocks on door top and base

摘要

The device is for correcting door warping, and is especially applicable to an external timber door which warps due to temperature differential and moisture absorption, and has braces which extend between a mid-door height lock plate and the top and bottom door corners. the braces are in rod form, hooking onto the lock plate, and extending through corner anchorage blocks to receive locking nuts. Adjustment is effected at the anchorage by rotating the nuts on the threaded rods or in the lock plate vicinity by a horizontal bolt and counter plate assembly with the bolt engaging the lock plate.
