By attaching this mechanism to any brace, piece of wood or steel, it can be made adjustable simply by turning the handle. It works like a C-Clamp that will push or pull. It can be used in place of a bar or pipe clamp, and can be made any length by using a 2x2 or 2x4 piece of lumber. Using it, any object or aircraft part can be moved into its exact required position, within a 1/64 of an inch, simply by turning the handle. It is a large turnbuckle with attachment plates at either end. It can be used to plumb walls, square up framing, pull together studs and joist (or push them apart) and straighten warped structural members for fixing in place. It can exert up to 2000 lbs of force with 80 lbs of force on the turnbuckle handle. In most common use, one plate is screwed to a 2x4 and the other to a stud wall or post. The free end of the 2x4 is then nailed or screwed to a joist deck, floor, etc. Maximum travel is 7-3/4”. | |
