GRS STANDARD ENGRAVING BLOCK
The GRS Standard Block gives you outstanding quality, strength, and value. At 19lbs. (8.6kg), it is up to 25% heavier than similar competing blocks. A massive roller bearing system inside always turns smoothly and prevents wear.
This block also includes the GRS rotational brake which lets you adjust the rotational resistance from completely free to solidly locked. The finish is low glare to reduce eye strain. Every major part is machined from solid steel; no cast metal is used.
Included are upper jaw plates, 4 pins, and a wrench.
