Mike, I'm sure that by now you've already installed the casters on your grilling table and had plenty of use for it, with the casters securely fastened with three substantial screws in each leg, however, I'm seeing a potential problem with your choice of casters. The problem I'm seeing in my mind's eye is that when your overly rambunctious dog (or alligator, tiger, or whatever) gets their leash tangled up in the table, and they take off for parts unknown, you may have wished you had gone ahead and gotten casters with a locking mechanism on them! Admittedly, that may not stop them from making off with yer brisket, but it may slow them down enough that your son (or daughter) can catch up to them and at least rescue the entrée!

I expect so, but if you let them sit on carpet, you will want small cups to protect the carpet.
