You can hold your workpieces reliably in position using the four plastic jaws provided, which give you a variety of clamping options, as well as two pipe clamps for securing round workpieces. The MASTER 650 ERGO provides a clamping width of 110 mm between the tabletop boards, or up to 410 mm between the plastic clamping jaws. In the highest position, you can also easily vertically clamp workpieces with a width of up to 80 mm. The extension plate provided lets you quickly and easily extend the coated tabletop (made of FSC-certified MDF with chamfered edges) to form a continuous work surface measuring 650 x 490 mm, to hold larger workpieces.
