The cleat, also known as a bitt, is a mooring component that is fitted to the side of docks using T-head bolts and stainless-steel nuts. At AISTER, we are experts in designing and manufacturing mooring cleats to meet the requirements of all sorts of berths. We provide a wide range of cleats in three different sizes: standard, which can withstand up to 4 tonnes of tension, reinforced, which can withstand up to 6 tonnes, and super-reinforced, designed for mooring mega yachts and fishing vessels and with a tensile strength of 10 tonnes. All three models are manufactured from marine-grade corrosion-resistant aluminium.
When most people hear the word bollard, they immediately think of the small, round posts made from stone or iron that are used in cities to prevent parking or stop vehicles from entering a certain area. However, when it comes to the sea, bollards are used for something else: security and mooring. Two properties required by ships at any dock in the world. As such, bollards form an essential part of sports, fishing and commercial harbours, just like cleats. These two conventional mooring systems are used to ensure a boat is fixed to the dock in a solid and secure way.
