30mm plain bearing swivel block

The 2030PSC plain bearing swivel block is manufactured using 100% recycled plastics and Allen's recognisable stainless steel side cheeks. 

The swivel on the head of the block allows the block to rotate to which ever angle is best for the sheet.  Ideal for elastic take-up systems.  This block looks very similar to the 30mm dynamic version.  To differentiate Allen have changed the sheave colour to grey.
