2" Long Stem Nylon Garage Door Roller
The standard garage door roller has a wheel that is 1-3/4 inches in diameter. They are called 2 inch rollers because they are used in 2 inch tracks which is standard on residential and most commercial garage doors. The nylon wheels with 11-ball bearings make the rollers quieter and roll more smoothly through the tracks and have an average life expectancy of 20,000 cycles.
