Check the listing for details. Garelick Boat Adjustable Table Base 30- 15 Inch - shock assist NICE READ. Condition: New other (see details). Listed at 250.00 USD. I will describe this to the best I can. This table Mount is adjustable and it has a hydraulic assist Ram inside of the pedestal when you let the adjustable stop out it lifts up on its own. And all you have to do is push the table back down and tighten the adjuster back. It measures 15 in when it's compressed. 30 in when it's open. Below the base there is an 8 and 1/2 in piece of the pipe that goes into the floor and it comes with the bracket to mount it to the floor. Very nice piece. Never installed. Has a couple little scratches from sitting in the shop. Besides that this thing is ready to go and it is a nice piece. I would keep this for myself if I had a cuddy boat I'll answer any more questions I can. Please make sure this will fit your application before you buy.
