The Axler QRA-501L Quick Release Assemblygives you the freedom to remove your camera from a tripod, stabilizer, or support rig without having to spend time unscrewing it from the device.

The longer plate length offers increased sliding range for balancing larger or heavier camera rigs. The plate includes 1/4"-20 and 3/8"-16 camera screws for use with a variety of cameras, and features three built-in bubble levels to assist with leveling. 1/4"-20 and 3/8"-16 threaded holes on the underside of the adapter are provided for mounting to tripods, stabilizers, or other support rigs.

Related Questions and Answers

Q: 1. Will the QRA-501L fit the Manfrotto ball head on a 055xB tripod. And does the assembly come as bottom tripod plate and a quick connection to camera or accessory? I need more stable platform to hold 22#.

A: What you see is what you get. There is a bottom plate with screw holes to accommodate any tripod quick release plate. Then the QRA-501L's own quick release plate that you attach to the bottom of the camera slips right into bottom plate. Once mounted, be sure to clamp the plate with the ratcheted lever. If the lever is blocked by the camera body and cannot tighten, pull the lever out and move it into a good position, push in and then tighten. Do this as much as needed, usually no more than 1-2 twists.

Q: 2. Can I mount this Axler QRA-501s quick release assembly onto my manfrotto 700rc2 fluid head?

A: Yes, but you'll need to swap screws on the 700rc2 plate. I believe the axler comes with a spare. I own a few they work great, just gotta be careful with placement as the tighten knob cuts a little close for comfort.

Q: 3. I know it is not listed in the description, but could I slide in a 500PLong plate?

A: Yes you can.

Q: 4. Please let me know if this adapter can be used with PROAM USA stabilizer?

A: While this Quick-Release Assembly will connect to the ProAa USA Autopilot Stabilizer we recommend smaller options because of the stabilizer's size. The Manfrotto 394 Low Profile Quick Release Adapter with 410PL Plate would be a better fit on the ProAm Stabilizer.

Q: 5. Is this compatible with 500plong plate?

A: Yes this has the Manfrotto 501 QR system.

Q: 6. yes i have a sunpak 7000 tripod will this work on it

Q: 8. Is this compatible with BeFree Compact Travel Carbon Fiber Tripod (Carbon) , B&H # MAMKBFRC4BH?

A: how would I know?

Q: 9. would i be able to mount this to mefoto ball head?

A: From the pictures it looks like yes. There looks to be a 3/8 screw hole in the bottom that would allow you to mount it to a ball head system. I don't own this product but I have one similar from manfrotto that will mount to the ball head 3/8 .

Q: 10. Would this plate fit on a Sachtler Ace 1011?
