Lewmar block upstands are designed to hold a block to the deck in a vertical direction for sail control in leisure marine application only. Their performance depends heavily on the specific application and suitability of installation.
Care must be taken during installation to ensure the block upstand is suitably aligned to the expected load. The load direction should be as close to perpendicular with the base as possible, which will maximise the working load of the pad eye.
