Made from computer-machined aluminum allowing for gentle, smooth curves, the totally new M-Series blocks are extremely light, yet strong. Combine this light weight with Schaefer's legendary quality and the result is an innovative line of new blocks with an incredible strength to weight ratio. Machined body follows load patterns creating a very high strength to weight ratio. Torlon® rollers and Delrin® ball bearings help ensure smooth adjustments with less than perfect leads.
