will this fit the Quantaray qsx 9500 tripod Quick Release Plate
or do you have original plates for this tri pod ?
My primary tripod is an old Bogen 3040 that uses this style of plate. Since I mostly use older Leitz glass, I prefer the 3/8" threaded bolt that attaches to the lens body. It is stronger than the 1/4" threaded bolt that is used on domestic gear.
Bogen was bought out by Manfrotto some years ago and this style (hexagonal) plate is used by other tripod makers. In 2012, I purchased some additional plates made by Manfrotto and they are identical to the original Bogen ones.
I am not familiar with the Quantaray tripods. Thus, I am not certain that it uses the Manfrotto-style plates. It appears that the tripod uses a square plate.
You really should 'Google' this item and note the technical specs and reviews for it.
