5 of 5 casters with brakes and not December 15, 2014
Reviewer: Anne from Syracuse, New York  
ordered the 5-shelf 30x60x72 shelf - am loading with lots of fabric.  talked to my son about how to move the shelving so it could be out of the way, yet allow access to both sides.  He uses a similar set up at his job and suggested the rubber casters.  You really have no idea how heavy fabric can be but on shelving this large, its really heavy.  I had to move the rack to get to other things in the basement and it moved really easy.  great job
