I have 60 sets of 5ea dual wheel chair casers still in the plastic sleaves. They fit many brands or chairs and can replace single wheel casters. Dual wheel casters that work properly won't where out your carpet and let the chair move easier too . I want $5 per sleeve of 5 but I will take an offer for the lot of sixty sleeves. They are in shipping boxes and can be ups'd to you if you are a resaler from out of the region. Call for more info. Thanks Craig. 401-290-8906 Location: No RI it's NOT ok to contact this poster with services or other commercial interests rhodeisland
