The table you are putting this on can not have a lip under it. The clamp needs to have flat space under the table to be tightened.  I use this arm on my 30" table. But, I have a spare 48" arm for tall dogs. Comes with a cheap groom loop, I recommend upgrading the groom loop to one I search groom loops on my site. All Sales Final.
