Boat owners, listen up! This adjustable pedestal base will seriously upgrade your seating setup. The height adjusts from 11.34 inches all the way to 17.24 inches, so you can find that perfect viewing position whether you're fishing or cruising. The black powder coating is tough stuff - it handles saltwater, sun, and all the harsh marine conditions without rusting or corroding. Installation is straightforward with pre-drilled hole patterns that work with most standard seat models. The positive locking handle made from stainless steel components keeps everything secure and stable, even in rough water. What's really handy is it works with swivel devices too, so you can create a fully rotating seat setup. The machined base provides serious strength and safety - no wobbling or weak points here. Weighing about 2.75kg, it's sturdy without being overly heavy. Perfect for most boat seat installations and way more affordable than you'd expect for this quality. Your back will thank you for getting the height just right!
