These Mizugiwa boat cleats are built to handle marine conditions! Made from 316 stainless steel - which is the good stuff for saltwater environments - these 4-inch cleats are corrosion-resistant and seriously durable. Each cleat measures about 10cm long (that's 4 inches), 2.3cm high, and 1.5cm wide, with hole centers spaced about 30mm apart. The non-handed design means they work equally well on either side of your boat, and you can even use them on docks, pontoons, or finger-berths for shore applications. The pack comes with four cleats, which is perfect for outfitting both sides of your vessel or having spares on hand. The silver finish looks professional and should hold up well against the elements. Now, just a heads up - fasteners aren't included, so you'll need to supply your own bolts or screws for installation based on your specific setup. The 316 grade stainless steel is what you want for marine use because it resists rust and corrosion much better than regular stainless steel. Whether you're replacing old worn-out cleats or adding additional tie-off points to your boat, these provide reliable performance for mooring, docking, or securing lines. The construction feels solid and well-made, and at this price for four cleats, it's a pretty good value compared to what you'd pay at most marine supply stores. If you need dependable cleats that can handle the tough marine environment, these are definitely worth considering for your boat or dock setup.
