The aluminum frame features snap latches that make set-up and break down a breeze. The included Speedy Cranks help you assemble the frame and legs with hardly any effort. The frame sections fold when not in use making storage simpler.The screen surface features a reinforced black binding that attaches with metal snaps. Height adjustment on the frame is in 6" increments which comes in handy when the size of your audience changes.
