Boat owners and bar stool enthusiasts, this DGQ 360 degree swivel base is exactly what you need for smooth, reliable rotation! Made from thick steel with a corrosion-resistant black powder coat finish, this thing is built to handle the marine environment without rusting out on you. The 6\ x 6\ square design with standard 5\ x 5\ bolt pattern fits most boat seats and bar stools perfectly. With 46 ball bearings inside, you get buttery-smooth rotation that doesn't feel cheap or gritty. The zero-tilt design means your seat stays level while you swivel - no awkward leaning when you turn to face different directions. Installation is straightforward - just bolt it between your seat and mounting surface and you're ready to go. Perfect for fishing boats where you need to quickly turn to face different directions, or for bar stools where swiveling makes seating so much more convenient. The heavy-duty construction means it won't wear out after a season of use like some cheaper swivels. Whether you're installing it on your boat, in your van conversion, or under your bar stools, this swivel delivers professional-grade performance without the professional price tag. Stop struggling with stiff or broken swivels - this one actually works like it's supposed to!
