Review on Sea Dog 588010 Flush Mount Holder by Sean Moran

I bought these for a 2 hole 15/16 inch table. The 3" deep holders fit snugly with just enough clearance for them to move around a bit and get in and out easily. Then I realized I needed a shorter depth for one, so I ordered a 2" deep. It fits well and neatly, doesn't move at all, and has enough resistance to get in and out to be sure and not get out. with a cup. Both sizes are 2 7/8 inches at the bottom and I would say the 3 inch depth is also 2 7/8 inches just below the rim. The 2 inch depth appears to be 2 15/16 below the rim.
