Tilt top Table Catches date back to the 18th century where they were originally used on tea tables. The unique design secures table tops in both flat and upright positions. When flat, table top is held in position by catch. When upright, catch is released. Easy to use, spring loaded mechanism with thumb release provides smooth transition between level or vertical positions. To install surface mount catch to underside of table top, strike mounts to pivot block or pedestal requiring slight mortising.
