How to Use Sinclair Buck-Ups

Setting a doorframe or window sash in the correct position and keeping it there can be difficult. A buck-up (or buck brace) holds a frame in place while craftsmen work around it. Sinclair buck-ups are telescoping, lightweight metal poles with clamps on each end that can be rotated into almost any position, which makes them easy to use. All that is required is an area to which you can secure the clamps of the buck-up.

  Attach the other end of the brace to an area where the buck-up is away from any workers and will hold the door in place. The Sinclair buck-up can reach up to 15 feet.

  Check the levels after the clamps have been set. Adjust the positions of the clamps to keep the frame level.
