The Sachtler Adapter for 75mm aktiv Head to Slider is an add-on accessory for Sachtler aktiv fluid heads like the one found in the Sachtler aktiv14T MS Flowtech 100 Tripod System. This adapter is necessary to mount Sachtler SpeedSwap heads to sliders, since those heads don’t use a traditional mounting screws. This adapter will only work with those fluid heads, but can mount to any slider or support gear with a 3/8"-16 screw or threading.
