The 488 Series high-resolution vertical lab jack provides a large mounting platform, lockable motion, and a novel mechanical design that virtually eliminates all backlash and provides a rock-solid, wobble-free mount at any height.
A scalloped adjustment ring provides non-rotating vertical travel over 1 in. (25.4 mm) of travel with 0.01 mm graduations. A recessed locking screw securely fixes the mount at the desired height to prevent inadvertent adjustments. The lockable, rotating platform has a knurled rim for coarse adjustment with graduations every 2°.
