The Kirk QRC-4.2 Arca-Type Quick Release Clamp Classic Knobfrom Kirk QRC-4.2 Arca-Type Quick Release Clamp Classic Knobis a 4.2" long clamp that is compatible with most Arca-type quick release plates.

This 4.2" quick-release receiver features a classic locking knob with a large knurled design. The clamp design also insures that no internal mechanisms are exposed, improving the clamp's resiliency.

The clamp features a single spirit level to assist in proper leveling and centering lines for accurately positioning your camera within the clamp. A captive release knob has also been added to prevent the accidental loss of small internal parts and an internal slot has been added to hold the included 5/32 hex wrench.

Q: 2. 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).

[Yes] Great American made quality. Next to RRS, Kirk makes the best plates and clamps. 5

[Aluminum] Have several Kirk products and love them all. High quality, great design, easy to use and very universal. Good value products. Have some that are 25 years old! 5

Claude	24/08/2024
[Yes] This item is very well built and solid. I would recommend it to anyone needing a smooth and quick release performance. B&H is always well stock with fast deliveries. Job well down guys! 5

[Arca-Type] I have several Kirk items and have been impressed each and every time. The build quality, made in the USA, and the mechanics of the product are smooth and user-friendly. Everything is in the right place and allows you to work easily without having to think about it. Also, I have to mention their cost - much less than other highly touted products and easily their equal. Try it once and you will be back. 5

[0.435 lb] Works well and is easy to use. Be sure to remember to get a reducer bushing to screw it to the tripod. It cost me several days because I forgot to order one. Once the bushing arrived the clamp locked to the tripod in a jiffy. I'm using it with an L-bracket. 5

Matt	11/08/2024
[Yes] I added this to my monopod to make it easier/faster to put the lens on. Having the little screw that keeps in it place is a great feature! 5

[Yes] Great product. Exactly what I was looking for. 5

[Arca-Type] The headline says it all; simple and sturdy. No quick release, no fancy buttons, just a simple rigid platform for your photographic equipment. In my case, I'm running a Matterport camera on a Manfrotto 290 tripod. while another brand QRC was recommended, I opted for the Kirk after holding both in my hands. I found the quick release on the other brand to be a potential issue down the road. I also like the hex wrench that comes with the Kirk, perfect for the legs on my Manfrotto tripod. So another win. A second bubble level would be helpful, but if you know to level things off before mounting your camera you'll be fine. If you need an Arca-type clamp for your work, the Kirk QRC-2.6 Arca-Type is basically a no-brainer, and B&H has them in stock and at the right price! 5

[Screw Knob] Another precision-machined metal work of industrial art by Kirk that serves its purpose perfectly. Very light. I've mounted mine to a metal Manfrotto tabletop tripod as a replacement for the 1/4 inch screw-in metal disk on the top of the tiny ballhead. This is so I can use that small tripod with small Arca-Swiss type camera plates that have no hole for a 1/4 inch screw. 5
