2010 GMC C6500 Truck - 16ft Box (Grip Truck)
$400/day$1,200/wk

A 4 x 4ft solid floppy — opaque black fabric on a hinged frame, blocking light completely. The smallest of the large-format cutters, and the one a single grip can rig alone.
Cuts light instead of adding it — block sun off a background, kill spill from a fixture, or add shape to a face with negative fill. Controlling where light ISN'T is half of cinematography. The 4x4 covers tight, single-subject work.
Rig between the source and whatever you're protecting. One or two C-stands with grip arms; bag every stand.
