ABSTRACT:
A door or window floor clamp provides opposing compression legs pivotally mounted onto opposing base legs and supported in upright attitudes by opposing telescoping braces. The braces are adjustable and extensible with latches provided for positioning the braces on the base legs and for locking the compression legs in place. The clamp folds so that the base legs, the compression legs and the braces are all in parallel adjacency for compact handling and storing.
