Q: 1. Is this for a 1/4 20 or 3/8 20 screw from below?

A: This has a 1/4"-20 Female threading.

Q: 2. Will this mount on an Arca Swiss P0? TIA

A: Sorry, no because the Kirk clamp has a threaded 3/8-16 hole and the Arca Swiss PO clamp has a M6 non-threaded hole.

Q: 3. I repeat my question to make it more understandable.I want to mount the 2.6 Kirk Quick Release Clamp on a DYH-90Ri Sunwayfoto leveling bracketI need to know: Is the Kirk 2.6 flat head screw 6mm or 1/4 ?Because the 3/8 to 1/4 adapter to be placed in the base of the leveling is standard, but a 3/8 to 6mm adapter must be made to measure

A: As per the manufacturer, the QRC-2.6CS is designed for tripod heads that have a raised key on the stem as well as 1/4 -20 or 6mm thread. With that being said, this clamp will not work on the DYH-90Ri. A more suitable clamp is the Desmond DAC-X1 50mm Quick Release Skeleton Clamp B&H # DEDACX1, which includes a 1/4 -20 bushing to fit the DYH-90Ri.

Q: 4. Does this version that B+H carries have the smaller safety stop that the version on Kirk's page does?

Q: 5. Will this work with the Manfrotto 502AH Pro Video Head with Flat Base, will the adjusting nob on the clamp have enough clearance from the flat base on the video head for proper operation?

A: The Kirk QRC-4.2 Arca-Type 4.2" Quick Release Clamp with Classic Locking Knob won't allow you to move the knob as it will hit the top of the Manfrotto 502AH Pro Video Head with Flat Base. Because you're using this large video head, you would need the Kirk 4.2" Quick Release Clamp with Extended Knob (https://bhpho.to/3QXSKT2).

Q: 6. Is the clamp compatible with the Benro B5 head?

A: Unfortunately, Benro does not give information on how to change the included clamp to the Kirk QRC-4.2 Arca-Type 4.2" Quick Release Clamp with Classic Locking Knob. The size of the screw, threads of the screw, and even if it is interchangeable is not listed, unfortunately.

Q: 9. Does the 2.6 Kirk Quick Release Clamp use a 6mm flat head screw or a 1/4 flat head screw?My question is because the 3/8 to 1/4 adapter is standard, but the 3/8 to 6mm adapter needs to be custom-made

A: It comes with one of each, so you don't need to custom make anything.

Q: 10. Can you change the Befree Live plate to arca-swiss?

A: No, the RC5 quick-release is integral to the BeFree Live fluid-head and not removable. If you want to us the fluid head then you'll have to use an adaptor block, like the Kirk QR-AB1QR, with the BeFree's RC5 camera plate.
