Description
The RAP-B-304U-TRA1 is a low-profile RAM® Track Ball™ base with a drill-down receiver that mounts to a flat surface. The included B Size 1" Track Ball™ slides into the receiver and tightens in place, creating a compact mounting point for compatible RAM® B Size arms, holders, and adapters.
This component is useful when you want a semi-permanent flat-surface base with the ability to quickly remove the ball mount when it is not in use. It is commonly used for small handheld electronics such as phones, action cameras, GPS units, and small tablets.
