GRS Magnablock

Includes upper jaw plates, 5 pins, and wrench.

GRS Magnablock gives you outstanding quality, strength, and convenience. Weighing 30 lb (13.7 kg), this extra-heavy block adds more stability to your work, especially when using power tools or chasing hammers. Inside Magnablock is a massive ball and roller bearing system that always turns smoothly and prevents internal wear. Magnablock includes the GRS rotational brake which lets you adjust the rotational resistance - from free to solidly locked.

All surfaces are specially finished for low glare to reduce eye strain. Magnablock jaws have replaceable threads - another GRS exclusive. Every major part is machined from solid steel - no cast metal is used.
