Alphatron Side Flag Kit for 4x5.65 Matte Box

This Side Flag Kit for Alphatron 4 x 5.65 Matte Box from Alphatron Broadcast Electronics adds adjustable side flags to your Alphatron 4 x 5.65 clip-on or rod mounted matte box.

Each flag uses a friction hinge that you attach to your matte box via the pre-drilled holes.

The flags expand vertically to meet the top flag minimizing gaps between the top and side flags.

The kit includes the two side flags, friction hinges, and an extra-large top flag.
