Q=Mount Quick Release
Arca-Type Manual-Locking Quick Release Adapter
The Q-Mount Quick Release from Novoflex is a clever Arca-type manual-locking quick release adapter. It differs from the Q-Base by being a manual quick release system. A safety pin in combination with the interchangeable Novoflex Q-Plate mounting plates prevents the plates from slipping out in either direction, while the double thread makes mounting simple; a fraction of a turn secures the plate. An Allen-wrench activated anti-twist pin prohibits loss of friction between the Q=Mount and tripod head.
The Q-Mount is compatible with Novoflex's optional system of matching camera plates and L brackets. It is also compatible with many other Arca-type quick release plates, available separately, though these will not be compatible with the safety pin function (the safety pin can be retracted if necessary). This adapter can be used with all conventional tripod heads or other mounting units with a 1/4" or 3/8" stud.
