Allen 30mm dynamic blocks are super smooth, high performing and ultra-reliable. Available with a wide range of accessories and features to suit most control line applications on dinghies and keelboats.
Dynamic Bearings - Twin rows of stainless steel ball bearings running on a stainless steel axle provide superior rolling speeds and durability when compared to plastic alternatives.
Ultra-Strap – A stainless steel strap which holds the block together and provides a strong, reliable and rope friendly attachment point.
Becket – The hole through the middle of the block can be used as a tying off point (becket).
Maximum Working Load – If exceeded the block may not perform as designed.
Breaking Load – The load at which a major block failure is likely to occur.
