Lewmar, Block Synchro Double, 40mm

The 40mm SC double control blocks from Lewmar are extremely light and have a high load capacity. The double blocks are designed with stainless steel bearings and are made from extremely resistant and durable composite materials. The open design of the bearing allows dirt and salt to be flushed out of the bearings, which makes maintenance and care of the blocks extremely easy and contributes to smooth running. These blocks are recommended for use with medium and dynamic loads, e.g. trim lines, mainsheets and genoa sheets of dinghies and small keelboats, spinnaker sheets, barber haulers.
