Abstract: A tool for mating, clamping, and gluing under high pressure, two picture frame members, the ends of which have been precisely cut prior to clamping. This high pressure produces a stronger joint than is now available in existing clamps that only hold the adjacent times while the glue is setting. It also produces a faster glue setting time than conventional clamps since excess glue is squeezed out, thus increasing clamp efficiency by making it available sooner for the next glue joint. In addition, it embodies an optional vertical clamp, which, in conjunction with a transparent triangular plate, applies a vertical pressure on members that may have been slightly warped or inaccurately cut. The triangular plate is optionally used with complex profiles to distribute the pressure. This combination results in a tight aesthetic joint. Existing clamps on the market do not embody this feature.
