Made from computer-machined aluminum allowing for gentle, smooth curves, our totally new M-Series Blocks are extremely light. Combine light weight with Schaefer's legendary quality and the result is an incredible strength to weight ratio.
These blocks feature Torlon™ rollers and Delrin™ Ball Bearings. The machined aluminum side plates will stand the test of time and will outlast most blocks made of plastic or composite material. M-Series Blocks are available in a variety of configurations to fit any application.
