Ash block configuration and specifications.

Block Configurations - Ash Blocks (stainless bindings)

Confusion quite often reigns, so a few words of explanation might help here.

With blocks, the "number" ie single, double, treble and so on refers to the number of sheaves (pulley wheels, if you must!).

If the binding - in these cases the metal bit, extends past the shell of the block, it forms a "becket" to which you can attach the end of the rope.

And that gives you the basic variations eg double, single & becket etc.
