The 1500 Series Standard-Duty Pocket Door Frame is designed to carry heavy standard size doors (up to 200lbs each) in standard 2 x 4 timber or steel framed stud walls. The 1500 frame kit is packaged for easy transport and fast installation for either single door or converging door applications. The 1500 is a versatile frame and can be adapted for use in non standard wall thicknesses, block masonry walls and can be cut down to accept any smaller size door size.
