Rutgerson 50mm blocks – the entire collection in the same size range
In the Rutgerson 50mm blocks product group, you will find 50mm size blocks in six different designs: basic block (B300501B), block with hunsvot (B300502B), model with hunsvot and quick lock, block with lock (B300503B), and a combined model with lock and hunsvot (B300504B) and a special model with a violin block (B300521B) for narrower installation spaces.
The swivel allows the block to rotate according to the rope pull angle, which reduces rope wear and keeps the power transmission efficient when the rope is not coming directly towards the block. The lockable model, on the other hand, holds the rope in place without constant holding, similar to a separate rope lock, but integrated directly into the block – this saves space on the deck when a separate lock is not needed at the same point.
The violin block is a narrower and lower model that is suitable for tighter installation locations where a regular block cannot turn without obstruction. Choose a model depending on whether you need just a change of direction (basic block), rotation (hunsvotti), locking or all together - combination models are more expensive but save space and installation work compared to separate components.
The basic block of the B300501B model is suitable for situations where only a change of direction is needed without additional features, while the B300502B with a hunsvot turns with the rope pull angle and thus reduces rope wear under uneven loads. The version with a quick release allows the block to be quickly removed and attached without tools, which is useful if the block changes position depending on the sailing situation.
The B300504B model, combined with a lock and a hunsvot, offers full functionality in one component, saving space on deck compared to a separate rope lock and block combination. Always check the thickness of the rope being used in relation to the groove in the block wheel - a rope that is too thick will not slide freely, which will significantly increase friction and wear.
Rutgerson is a Swedish, respected manufacturer of sailboat fittings and blocks, and the 50mm size range covers a large portion of the trimming needs of mid-sized sailboats – always check the thickness of your own rope in relation to the block's stated maximum capacity before ordering.
It is worth checking the pulley regularly to make sure the wheel is spinning freely – a stuck wheel increases friction and wears out both the rope and the pulley itself faster.
The color-coded packaging of Rutgerson blocks makes it easy to quickly identify the correct size when multiple blocks are used on the same boat.
The hull of Rutgerson blocks is made to withstand constant UV exposure and salt water without losing its shape or functionality over several sailing seasons.
