The Benro SP06 Ground Spreader for Twin Leg Tripods is especially designed to provide extra stability to tripods when used on uneven terrain like on stairs, or in the bleachers. It is an adjustable, locking ground-level spreader for use on difficult places to get stability for your equipment. The most notable advantages of a ground spreader over a mid-level spreader are faster set up because the spreader tends to unfold itself and the ability to put weight on it for added stability.
