Catamaran / A-Class / Blocks / 60mm dynamic blocks

Allen 60mm dynamic blocks offer low friction performance in a lightweight body. This range is ideal for fast-running control lines and sheets on keelboats, as well as more demanding applications such as backstay purchase systems. Also, a great choice for high-performance catamarans. Available with a wide range of accessories and features.


Swivel Lock - Single variations feature a built in swivel lock switch, located at the head of the block. Muti sheave options feature a removable swivel lock moulding.  


Dynamic Bearings - Twin rows of stainless steel ball bearings running on a stainless steel rail provide superior rolling speeds and durability. Great for fast running lines.


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.
