Inquiry (采购产品): Replacement Casters I have an aluminum four step rolling ladder in need of four casters. I'm not sure if the *PR-2 (2" replacement casters) are the correct fit. The ones I have are a 2" spring loaded caster with a shaft that's a total of 4 3/4" long. The shaft is in two diameters which include +/-1 7/8" x +/- 9/16" nearest the caster and a threaded piece +/-2 7/8" x +/- 5/16" with a nut. Can you help with replacements? Please let me know.
