Garage Door Roller Diameter and Stem Length

Garage Door Roller Diameter and Stem Length

Garage door rollers come in a variety of shapes, sizes, and materials as pictured and described below.
Roller sizes are fairly standard in the garage door industry. Most residential rollers are referred to as two-inch, but the roller diameter is actually closer to 1 3/4 inches. Commercial and industrial doors use two-inch and three-inch rollers. The wheels on three-inch rollers measure closer to 2 3/4 inches. You can figure out this measurement with a ruler across the face of the roller. In addition to the diameter of the roller, you need to know the length of the stem as well. You can get that measurement by measuring the length as pictured above. The shafts or stems on all our rollers are the industry standard of 7/16 inch.
