Nice fit and operationally flawless! Good casterJosef Ricketts - 07/17/2013Less plastic than the comperably-priced blue ones from Parts Express that I tried. The cutouts needed to be a little longer than 2" for the caster to fit flush, maybe 2 3/16". Great ValueDave Delfel - 04/12/2011These casters make my life much simpler. Great value for the dollar and super durable. If you have ever put wheels on anything you know quality = expensive. This is one exception.
