Low-profile Tiny Vise® clamps from Carr Lane Manufacturing are ideal for thin workpieces, and whenever downthrust action is not required. These mini edge clamps securely grip the side of a workpiece to keep the top clear for machining. Patented design features a slotted countersink to provide strong, reliable clamping force with the easy turn of a hex wrench. These compact clamps are ideal for fixturing multiple parts, small or large. Each clamp has both a serrated face (for maximum gripping) and a smooth face (to avoid marring finished parts). These clamps look so simple, but work amazingly well, with major advantages over earlier designs. Patent number 5,624,106. Made in USA.
