Eagle 5" Resilient Stem Caster
The Eagle 5″ Resilient Stem Caster helps you build a strong, quiet, mobile shelving unit. To begin with, it has a 5-inch diameter and a 1 1/4-inch wheel face. We also use EAGLEbrite® zinc on the caster. Furthermore, its resilient tread can handle a weight of up to 300 pounds.
In addition, this caster comes with a donut bumper. Finally, you should use it with 1-inch diameter posts.
