Related Questions and Answers

Q: 1. Does it come with any screw to for mounting to the FLM ball head?

A: For the FLM QLB-80 Quick Release Clamp, screws would need to be purchased separately.

Q: 2. 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: 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. does this clamp comes with an adapter bushing?

A: Yes it does, a 3/8 1/4 reducer. Just be sure and do not overlook it in the bubble packaging like I did initially. It is very small.

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 do you remove the safety pin?

A: Hi, the safety pin is not removable--it is spring-loaded and will retract into the body of the clamp if not in use.

Q: 7. Is this clamp Arca Swiss compatible and able to work on an RSS Arca Swiss L-plate?

A: Simply....YES.

Q: 8. Will this clamp modify a FLM CB-32 head to have a Quick Disconnect system?

A: Hi,Yes it will, but you should observe that the safety pin is for FLM plates and not necessarily compatible with other Area-Swiss plates. I own a RSS L-plate for the Oly OM-D E-MII and the pin is annoying. Perhaps the pin could be knocked out. You could also consider a RSS QR instead. Google that combination. Either way you should apply a locking glue to keep it securely in place. FLM has a guide for that.

Q: 9. What is the load capacity of this clamp?

A: MAX LOAD IS 45 kg (kilos) or 99 lb and 3.3283 oz

Q: 10. Will the locking pin mechanism work with the Feisol QP-144750 QR Plate?

A: Yes. No problem great fit
