50mm Dynamic Blocks
Allen 50mm dynamic blocks offer low friction performance in a lightweight body. Built to suit the more demanding applications on dinghies and sports catamarans. Also, a great choice for fast running control lines and sheets on keelboats. 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.
