Two parallel 1-1/4″ nylon roller trolley
This trolley-style assembly includes two 1-1/4" concave nylon rollers in a stamped steel housing. Designed for smooth integration into the bottom rail of the door, it's secured with two existing door screws, ensuring stability and ease of movement. The nylon rollers provide a quieter operation and reduce track wear, thus prolonging the lifespan of both rollers and track. Part# 5000785.
