3" Carriage-House Nylon Garage Door Roller with 9" Stem
Heavy-duty nylon roller with a long zinc-plated steel stem and precision bearing for compatible carriage-house and commercial garage doors.
The Carriage-House Garage Door Roller combines a durable white nylon tire, a sealed precision bearing, and an extra-long 9-inch steel stem for demanding sectional garage door applications.
Its nylon wheel helps reduce metal-on-metal track noise while the 6203-ZZ precision bearing supports smooth roller rotation under repeated use. The extended stem is designed for compatible carriage-house doors, thicker door sections, specialty fixtures, and other applications requiring more stem length than a standard roller.
9" Extra-Long Stem Provides additional reach for compatible carriage-house doors, thick sections, and specialty roller fixtures.
Precision-Bearing Design A sealed 6203-ZZ bearing supports smooth rotation and dependable operation.
Heavy-Duty Performance Rated for a 150 lb. load and 100,000 cycles on a properly installed 12-foot door.

Track Size Notice: This is a nominal 3-inch roller intended for compatible 3-inch garage door track. It should not be installed in standard residential 2-inch track.
Long-Stem Application: The 9-inch stem is significantly longer than a standard residential roller stem. Confirm that the existing hinge, roller carrier, door thickness, and required stem travel are compatible. An unnecessarily long stem may interfere with the door, track, framing, or nearby hardware.
Compatibility Notice
Verify the 3-inch track size, roller diameter, 9-inch stem length, stem diameter, hinge or roller-carrier opening, door thickness, door weight, track condition, and available side clearance before ordering. Matching only the wheel diameter does not guarantee proper fit.
Safety Warning: Garage doors are heavy and can move unexpectedly. Do not remove or service bottom brackets, lifting cables, springs, or other components under tension while replacing rollers. Secure the door before service and use a qualified garage door technician for heavy commercial doors or unfamiliar hardware.
