The professional 504HD-546GBK video tripod kit is a two-stage, extremely rigid, stable system able to counterbalance equipment weight up to 16.5 lbs. The tripod's floor-level spreader aids tripod leg angle setting adjustment.The Manfrotto 504HD video fluid head is a perfect balance of design and performance. The bridge design improves the head's rigidity and its PAN friction control is fast, simple to fine-tune and protected from knocks.All structural components are made from aluminum, with the PAN axis rotation unit uses ball bearings to obtain smooth, vibration-free controlled movements that can be directly adjusted using the head's FDS variable friction system. FDS on both the PAN and TILT axes also ensures that the head works perfectly at all temperatures, with all types of equipment and under all loads.Ergonomic lever and dial designs combine with the friction index to give you complete control over the 504HD. The 504HD has been designed to offer a load capacity of up to 7.5kg (16.5lb) making it suitable for a huge range of camera equipment.The CBS counterbalance system has 4 presets for a full range of camera weights (0, 2.5kg-5.5lb, 5kg-11lb and 7.5kg-16.5lb). Leveling the head is simple thanks to the 75mm diameter half-ball and the back-lit bubble level. Two 3/8” threads on the top plate allow accessories (such as monitors and arms) to be directly and securely attached to the head.
