This occasionally-used Giottos VGRN9224-S2N Aluminum Tripod Kit uses a 3-spiral thread locking system to allow tightening or loosening of the locks with one hand at the same time with a 1/8th twist. The tripod features three legs, a centre column, a leveling bubble, and two adjustment knobs. Each leg of the tripod has three rings for a maximum height of up to 58.3". Kit comes with a PU-40 Quick Release plate and carrying bag with zipper. It works great with no problems. I have personally found it to be very lightweight, convenient, and stable. I needed to sell it for another tripod that had a particular feature. Price is $140 firm. Posting will be removed once item is sold.
