Hi Frank,


Thank you very much for your note!  We do have this item available for special order and the special order for a 5 pack, B-stem, with a chrome cover has a product number of 50414.  Since it is special order it will take a little longer for delivery, but the cost per caster is not much more than what we have on our website. 


For special order casters you will need to call our customer service, who is more than happy to help with placing an order for special order casters.  866-501-6055.


We appreciate your note and we are here to help!

Superball Casters, 75 lbs./Caster, Vinyl, Black, 4/Set; How long is the stem on these? If optional can if be 2.5 in?

Hi Royce,


Hope that you had a great weekend and thank you for your question the length of stem on the Master Caster Superball Casters.  We put out an really useful guide on "How to replace your chair casters" and it explains the different sizes of stems, when to use hard vs soft casters, and even has nifty diagram of all the chair casters.  The stem on this Master Caster Superball caster is a "W stem" which would mean that it is 1 1/2" high and 5/16" wide.  Now as far as 2.5 inch high, you could use this in a deeper caster hole, but the main thing to consider is the width of the hole.  You really need it to be snug, so it does not move around, and the height is really less of a consideration.  I would suggest that you review the article link I attached and if you like the article then please like it on Facebook... you never know if one of your friends needs to measure a caster!


Please let us know if there is anything else we can do for you and we sincerely appreciate your great question.  We also have over 40,000 business supplies for next day delivery or bulk shipping and we hope you come back to see us again.


Take care!

Hi, I am looking for casters with sleeves, and this type of casters look good. Just want to make sure, is the sleeve included in product?

 MAS53516 Superball Caster Sets include plastic sockets that go inside base of your chair to help hold the casters in place.

Hi, I have questions about the dimension. I looked into the website, but there is no data about the total height of this product. Could you look into it or measure it and tell me? Thank you so much. By the way, is shipping free if I buy 3 sets of this product?

Master Caster Superball Casters have an overall height of 2-1/2."  We offer free shipping on orders over $75. Ordering 3 sets will put you over that threshold, so you will get free shipping.
