This Manfrotto/Avenger B140FXL stand is called a Flat Jumper since it is usually used to mount lights or butterflies above the top of the flats (walls) of a photo, movie, or video set. It has a 154 lb (70 kg)tolerance, even at its highest 14' (4.25 m) position. It features a ratchet lock crank handle for safety.
This unit is also available with pneumatic wheels (B140XLP). This stand differs from the 140XL in that its crank handle is fixed, and is not capable of folding back on itself.
Three sections, two risers
