KIRKLAND EXTERNAL RING CLAMP
The Kirkland External Ring Clamp, like its better known sibling, is
made of cast aluminum for years of service. This clamp holds a ring
externally which allows the user to file, grind or polish the inside. Jaws
are lined with thick leather and slightly concave so they will not
scratch gold, silver or other precious metals. Made in the USA.
Size 6"
