RAM Square Post Clamp Base 1.75"–4" B Size (RAM-B-247U)

Included:

• 1 x RAM Adjustable Square Post Clamp Base, B Size (RAM-B-247U)

The RAM-B-247U is an adjustable clamp base for square posts from 1.75" to 4" wide, including suitable forklift posts. Slotted holes allow the two clamp plates to fit different post widths, while the integrated 1" B size ball connects to a matching RAM socket arm.

Arm, holder and device are sold separately. Add a B size socket arm, then choose the holder-side connection to suit the holder. A holder with a built-in B ball can attach to the arm directly; a flat-backed holder needs the appropriate B size ball plate.
