Ronstan is a respected name in sailing hardware, engineering gear for smooth operation and dependable strength. The line covers blocks and pulleys, cam and clutch cleats, mainsheet and genoa travelers, shackles, and a wide range of deck hardware for running rigging and sail control. Known for quality ball-bearing blocks and well-made fittings, Ronstan gear handles control lines with low friction and holds up to the loads and the marine environment. From dinghies to cruisers to race boats, sailors rely on Ronstan to rig and upgrade their boats. For sailing hardware that performs and lasts, it is a leading choice.
Choosing the right hardware comes down to load and line. Match blocks, cleats, and travelers to the line diameter they handle and the working load of the application, since strength rating and sheave size affect smooth operation and safety. Match travelers and mainsheet systems to your boat size and rig. Confirm the fitting suits your mounting and existing hardware. Review the product details and load ratings against your setup before buying. With Ronstan hardware, you handle sail and control lines with smooth, strong, reliable performance.
Ball-bearing blocks roll on bearings that reduce friction under load, so lines run smoother and easier than on plain-bearing blocks. That matters for trimming and easing sails efficiently. Ronstan is known for quality, low-friction blocks.
Match the block to the line diameter it handles and the working load of the application. Strength rating and sheave size both matter for smooth, safe operation. Check the product details and load ratings against your line and use.
A cam cleat grips a line between spring-loaded jaws so you can quickly cleat and release it under load, common for sheets and control lines. Match it to your line diameter and load. Choose the cleat style that suits how you trim and where it mounts.
