Pacific Entries CDR2044-3084-15 sliding barn door hardware is made of stainless steel and can hold up to 150 lbs. It includes two stainless steel hangers, five standoffs, one U-channel floor guide, two end stops, two anti-jump discs, and five hex head lag bolts. The track is 65" long and the head casing should be a minimum of 6-1/4" tall x 3/4" thick. It is important to wear safety gear when installing the hardware and to ensure you have ample space to operate power tools. The door rolls on the track, so it is important to take precaution when moving it to avoid pinching fingers or hair.
