Manfrotto Spring Type 4 Blue

The Manfrotto FF3533 (Spring Type 4 Blue) is the official heavy-duty replacement/extension spring for the Manfrotto FF3533 Top 4C pantograph. This blue-coded spring is essential when using heavier fixtures (large softboxes, HMIs, or multiple lights) on Sky Track or Top System pantographs – simply swap or add it to perfectly counterbalance the increased weight.

The Manfrotto FF3533 blue spring is the strongest standard spring in the Manfrotto pantograph range. It replaces the stock spring in the Top 4C pantograph when the total weight of the mounted light exceeds the range of the factory spring. Installation is straightforward – the spring hooks into the same anchor points inside the pantograph arms. Using the correct spring ensures smooth, safe vertical travel and prevents the pantograph from drifting or crashing.
