RA QRB
Quick release bolt is designed for installations where the projector needs to be removed regularly. The QRB replaces the M10 retaining bolt connecting the Mount to a 50mm Column or Wall Mount, meaning it can be used in conjunction with any RA Mount Products which have an M10 retaining bolt including our RA3 & RA4 plus all our Centurian Entrapment Cages.
The image above shows the QRB being used with an RA3 Universal Mount & an RA1 Ceiling Mount Plate.
