The Glidetrack 30" Glidetrack HD & Manfrotto 502HD 3/8"-16 Head/Base Kit from B&H combines two items that greatly match to achieve a variety of professional-looking tracking shots with mid-size DSLR and camcorder rigs of up to 8.8 lbs.
The 30" Glidetrack HD (Heavy Duty) is of yet sturdier construction than the SD version and has self-lubricating 16mm rails designed for smoothness in getting tracking shots and glides at angles. It can be used attached to a tripod, or to two tripods, or can be placed to rest on its own two scratch-free feet.
Like the Glidetrack, the Manfrotto 502HD Head is also designed for smooth operation. It features Manfrotto's patented bridging technology that ensures pan friction control is intuitive and protected from knocks. Among other features are independent locks for pan and for tilt, as well as continuously adjustable drag for each.
The Glidetrack and Manfrotto are conveniently packaged as great matches in quality and function.
