This is our premium boom stand featuring a dual horizontal arm that slides effortlessly in a ball-bearing mount. It includes a weighted base, 24" vertical post, ball-bearing horizontal arm, safety collar, and your choice of either a 20mm or a 32mm diameter microscope mounting post. Per the manufacturer: "This dual arm boom stand is the gold standard of the industry and is in use in thousands of locations and applications worldwide. It supports an additional microscope weight of up to 23 lbs. (10.4Kg) fully extended."
The SMS6B ball bearing boom stand is optimized for routine inspection of large samples where fluid motion in a horizontal plane is required.
The horizontal arm is mounted on linear ball bearing units in the solid aluminum cross slider. Locking the arm in position is quick and easy with the secure soft-grip knobs. The stereo microscope mounting is via the industry standard 5/8″ bonder socket. Non-bonder style focus mounts are easily accommodated.
