How much weight can this mount hold?

The mount is designed to support up to 5-lb/2.3-kg.

Does the Friction Knob UMS swivel to allow easy access in and out of a wheelchair?

The Friction Knob UMS can be loosened at the center joint for re-positioning of all arm joints in any direction. However, none of the joints are strictly for swivel action.

Can this mount be attached to a table, bed or wheelchair?

Yes, the Super Clamp allows mounting to flat or round (tubular) surfaces up to 2” in size.

How do I connect a mounting plate to this mounting arm?

The Friction Knob UMS allows mounting plates with a ¼”x 20 mounting threaded stud to be connected directly to the end of the arm.

If you have difficulty connecting a mounting plate, it’s likely the mounting arm sections are backwards. The arm section with the reinforcing hex screw is the section that should be inserted into the Super Clamp. The opposite arm section should have the ¼”x 20 mounting thread to allow you to connect your mounting plate correctly.
