The Universal Suction Mount from Interfit is designed for use with the Strobies lighting accessories. Simply undo the locking nut to raise the suction cup seal. Wet the cup and apply the unit to a solid surface, push the unit onto the surface, and tighten the locking nut until a bond has been formed between the suction cup and the solid surface. To release the Suction cup, simply undo the locking nut whilst holding the unit steady and lift the release tab gently. Ensure that you hold the unit securely when releasing the tab.
