This is the Cramer Kik Step Base Bumper Replacement Part 46057801, the rubber ring that goes around "the bottom of the bottom" of a Kik Step to provide non-skid surface contact to the floor. Please Note: We do not accept returns of parts because the cost of returning them is more than the cost of the item itself. The product is inspected and is in perfect condition when it leaves here. If you have any doubts or questions, please call us before ordering. Please note that if your Kik Step is at least forty years old, this part cannot be replaced. You can tell by looking at the bottom of the unit where the base bumper should be attached. If the bottom is molded on rather being a rubber strip covering a steel lip, this repair part cannot be attached. If you have any doubts about it, you can either send us a photo of your Kik Step or call us and we will try to figure it out together. Actually, we're rather delighted there are folks using forty-plus year old Kik Steps.
