Rated 4.2 out of 5 by 9 reviewers.
Rated 5 out of 5 by Fits flush to the floor. Just installed two of the them on a PT 175 on the front deck so two people can spider rig. Install wasn't bad. But I like how flush they mount to the floor. Good product and they want be in your way when not in use. February 7, 2011
Rated 4 out of 5 by Pedestal bases Nice brushed stainless bases, Good welds, and look to be well built. Not the most fun to install in the floor of a newer boat, but got it done and couldn't be happier ( that is, unless you have someone else install them for you, but that's another story!) Just waiting for the ice to melt so I can get out on the lake now! January 17, 2011
Rated 5 out of 5 by NICE BASE SETS EVEN WITH FLOOR I love this base it sets even with the floor and leaves more room in the boat to move around and carry stuff when not in use. August 17, 2010
Rated 5 out of 5 by Quality Chair Base This base is better than the ones that came with my boat. As advertised, it is stainless steel with SS hardware. Had no idea what a sturdy chunk of metal this would be. May 4, 2010

A: 
Per the manufacturer, the plastic bushing will swell a little making it hard to remove the post. You might lightly sand or file the bushing or call the manufacturer and they could send some new ones. Thanks

Was wondering if seats fitted with the pin mounts will "swivel" in these base plates, or do they lock in position? Do you need to add an additional swivel plate?

whats the difference between threaded base plate and the base plate

A: 
I have used both, the threaded is just that the post base screws into the plate. I am currently using the king pin type this held in the base by compression and just pulls out when you want to remove it. Both work well, screw in will last longer, but has added cost on all items.

The threaded base plate is for seat posts that are threaded at the bottom and the regular base plate is for seat posts that are just the plain pin style.

A: 
If you can stand on the center of the hatch cover without it bowing or flexing and the hatch isn't to large, then you may be able to install one on it.

My Tracker boat came with one of these installed on the fiberglass rear storage compartment lid and it is holding up fine. My hatch lid is about an inch thick, but it is also 3 feet wide and 2 feet long. The smaller the hatch size the better. See if you can install a piece of 3/4" marine plywood (a little smaller than the lid) to the bottom of the hatch lid to add strength.

One other note, the bottom of the tube has no bottom on it, so water can run through it and down into the storage area.
