Hettich Grant Top Line Side Mount Sliding Door Hardware Set For Two 1-3/8in Doors

The carriers are the outstanding feature of the 7000 set. Each has four free-rolling nylon rollers mounted on pivoting rocker-arms which allow constant wheel contact with track. Each door therefore, rides on eight wheels. Slipping or jumping is impossible. The ball-and-socket suspension compensates for minor header misalignment. Hangers are secured by vibration-proof stop nuts.
