QUESTION What weight can they support? What is the width of the post? Does it come with shelf stoppers? If not, where can I buy them? Do you have casters for these posts? Can I use the aluminum shelves I already have? They are 6'x2.5'.
ANSWER Hello, according to the spec sheet, the posts are made of .065" thick square tubes notched at every 2" on each corner. A nylon cap is installed on the top and a nylon housing for a steel leveler is notched on the bottom. This spec sheet will be uploaded and available under the Literature tab for this product. This post does not include casters. The normal weight capacity for the unit without casters is 3,000 pounds total. We currently do not have casters for this post. Thank you!
