Price per set of 4 blocks. M6 SHCS with Nut and Washer included.
Blocks are 37mm long and suitable for any blade up to a 32mm wide band that is quite common for resawing these days. Blocks are 5/8″ square.
Case hardened with the block ends being precision ground so they align perfectly with each other in their slot in the backing plate.
The guide block have 4 working faces, so perhaps every 5-10 years depending on use and abuse they can be rotated to present a fresh side to the blade. Giving a realistic working life of 20-40 years per set of blocks.
