The Miller Off-Ground Spreader for HD Tripod is a heavy-duty mid-level spreader that can be used with the 3350 HD Tripod on even or uneven surfaces. It features spring-loaded attachment points that make attaching and detaching the spreader from your legs simple. Each arm of the spreader is individually adjustable in length. A locking knob on the center hub allows the spreader to fold when loosened, or it can be tightened to keep the spreader rigid.
