ABSTRACT:
A vise for thin objects such as doors has improved features that allows the doors to be transported on the vise and also accommodates various thicknesses of doors. The vise has a pair of jaws hinged together by a spring loaded hinge. The spring urges the jaws apart. The weight of the door overcomes the spring, drawing the jaws into contact with the door for support. Each jaw is mounted on a wheel for transporting. Each jaw also has an adjustable plate mounted on its inner side for varying the effective opening of the jaws.
