Carr Lane Manufacturing's Tiny Vise® M-series incorporates a modular jaw design for greater adjustability. This new modular system allows adjusting your workpiece engagement point by adding or removing spacers. This is useful when using the same fixture for machining a family of parts, or when workpiece size can vary somewhat between batches. Just like our original Tiny Vise®, these mini edge clamps grip the side of a workpiece to keep the top clear for machining. The 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. They look so simple, but work amazingly well! Patent number 5,624,106. Made in USA.
