S30 Ball Bearing Block Single Standup Loop Top
Series 30 blocks offer smooth running performance with low friction. These low profile, light weight blocks are incredibly strong. Typically used as primary lead blocks on dinghies and cats, they are also suitable for many control line applications on larger boats. Ronstan’s 2 stage ball bearing system provides consistant performance over the full load range of the blocks. The block cheeks are moulded in reinforced ‘Zytel’ for maximum impact resistance.
Single blocks are available with swivel head or two way loop head.
