a telescopically adjustable support brace is used to hold concrete form work at the proper linear distance during pouring operations . the brace comprises a pair of crossbars and telescoping adjustable arms that are locked by a pin inserted through aligned apertures . at the distal ends of each arm , a serrated cleat for digging into the form wall and prevent slippage . the cleats are connected to the arms by a threaded rod , permitting fine adjustments via mateable threads . the crossbars are connected by a pivot bolt or hinge . when the bolt or hinge is locked in place , the invention forms a horizontally rigid assembly , holding the concrete form walls or other objects apart . the hinge or bolt is released by drawing of a wire coupled through a retention member on a lock . when released , the brace pivots about the crossbars , permitting easy extraction of the brace from the forms .
