Wire Guide Blocks: Change the “R” suffix to “W” in the part number for blocks with tieoffs for arbor wire guides.

Tieoffs: Tieoffs for wire guided clews are also available.

RWL: The recommended working load (RWL) is maximum load that can be applied to a block which is in “like new” condition and has been properly installed, maintained and operated. The mounting of the head block has a major effect on the RWL, as shown in the tables.
