Q: 1. The adapter relies on 1/4-20 studs (from below on the original mounting plate, and from the top on the arca swiss block) to hold the entire assembly...what are the weight/torque limits on this kind of set up? How much should one trust a single 1/4-20 stud to hold big glass?

A: I would say that if you feel that way, you should trust your expensive glass to double 1/4" or single 3/8".

Q: 2. Will this fit on the Arca-Swiss Monoball P0? I know the 60mm diameter is a perfect fit, but I'm worried about the knob on the clamp clearing the lever on at the top of the P0. I know Sunwayfoto makes a clamp specifically designed for the A-S P0 that has an extra-long clamp knob so that it extends beyond the possible obstruction of the P0's top lever ... do I need something like that, or will this FLM SRB-60 be fine?

A: We see no issue if you use this with the Arca-Swiss Monoball P0 with Panning System B&H # ARMPOPS. In fact, we are of the opinion that this clamp will work better than OEM or other 3rd party clamps.

Q: 3. Is able to hold Manfrotto RC2 plate ?

A: As the RC2 is not Arca-compatible, it will not work with the FLM QLB-80 Quick Release Clamp.

Q: 4. Can the locking pin be removed?

A: The locking pin on the FLM QLB-80 Quick Release Clamp cannot be removed. However, if you squeeze the pin between a pair of pliers and push it down into the body of the clamp, the locking pin will be ineffective and out of the way.

Q: 5. I have Feisol 3442 with center column and P0 ball head, so the legs fold up over the ballhead and QR plate to make a very compact package. Do the protrusions on this plate allow the legs to fold completely? Because of the position of the QR knob, bubble level, and corners on my current square plate it is pretty fiddly to get it all lined up and fit into the Feisol carry bag.

A: The FLM SRB-60 Quick Release Clamp is very close. It has not been tested but if the clamp is 60mm it should just work.

Q: 6. How wide is the clamp in its narrowest dimension? i.e., what are the dimensions of the clamping surfaces?

A: The FLM SRB-40 QR Clamp measures 56mm x 38mm (excluding the knob). The fixed side of the jaw of the Arca-compatible clamp is 38mm long and the adjustable side of the jaw is 32mm long.

Q: 7. Will this just screw right on my FLM CB24?

A: No. the thread on your CG24 is 1/4"/20. The thread on the SRB40 is 3/8"/16 . But you can make it fit easily by using an adapter bushing. A good one would be B&H # WIBS100.

Q: 8. Can I use this on a FOBA Superball? My current FOBA clamp attaches with 2 countersunk screws 45mm apart

A: Yes, the super ball offers a 3/8 center stud screw and will allow the quick release plate to adapt nicely.

Q: 9. What is the spacing of the bottom mount holes in millimeters? Curious if this can be direct-mounted to Arri plates.

A: The FLM QLB-80 quick release clamp has each of the mounting points spaced 12mm apart.

Q: 10. Is this clamp Arca Swiss compatible and able to work on an RSS Arca Swiss L-plate?

A: Simply....YES.
