The Discal Clamp 64mm from Sunwayfoto is a Swiss-Arca-compatible integral screw-knob clamp with an anodized black finish. It has a captive knob, safety-stop grooves, and a hollowed-out design that reduces the weight of the clamp. You can use an M6 screw to mount it to an AS-style ball head, and it will accept any standard Arca-Swiss quick-release plate. This Discal Clamp also has an integrated bubble level.

Sunwayfoto DDY-64I Reviews
Using it to switch tripod heads. Bought the Kirk TQR Plates and works well. The only con I feel is that the clamp is only 20mm wide. It should have been more, so the clamping strength will be more with your heavy gears.
Great QR plate!
Well made. Has felt very solid with Sony A7R IV on it. No concerns with it failing. Has safety grooves too so if it did loosen your stuff won't fall off. It is 2.5 in diameter, not counting the screw knob, so you need to take that into consideration. Tis rather large! Anyway, I'm liking it and I recommend it.
This clamp fit my manfrotto 222 joystick perfectly. Now I can lock down my camera with the meike MK-xe3G hand grip with ease.
great item for arca swiss connections
I fell in love with this disk and now have a couple that I use almost daily. Simple easy connection with security
Falls short of being truly useful
Sunway's 64mm Discal Clamp is unable to open far enough to even accept Sunway's L-bracket (for the EOS 5DSR). It does work with some quick release plates. It is well made using good materials and its price is attractive. It may work for you, or it may not.
This inexpensive clamp is solidly made and works perfectly on my monopod. There's no need to purchase a more expensive clamp; this one will meet your needs.
Excellent for my purpose
I was looking for a way to swap my tripod heads on my tripod. I have a Ball Head, Geared Head, Video Head and Gimbal Head. Looked for several options and then found this clamp with 3/4 thread. So I bought 2 of them (58mm & 64mm) and attached to my 2 tripods. Also bought the Kirk couple of TQR-MPL & TQR-MPS for my heads. Now I can easily swap my tripod heads without any hassle and honestly speaking, the clamp is very well made with excellent clamping strength and I do not see any difference between this one and the high end ones. Go for it and you will not regret. The 58mm does not have a bubble level as mentioned in the BH description, but that is not a problem for me. Definitely worth recommending..
Does not fir some Sunwayfoto's QR plates
I wrote an earlier review praising this and it is well built. I did see a review where somebody said a Sunwayfoto L bracket for a Canon product did not fit and I thought.. That's crazy, right? Well, I was using my Sunway Discal clamp in the field yesterday and had on my Sony lens foot a Sunway DPG-62R QR plate..... and it didn't fit, wouldn't open wide enough. I could take off the safety screws and slide it in but that defeats the safety aspect of the two items. I have an RRS L bracket on my Sony A7R IV and an RRS plate on my A7C and they both fit into the Discal clamp, no problem. My Discal clamp is on a monopod. Sunwayfoto has to fix this issue on their plates or L brackets, or whatever, but for their own plates not to fit their own QR clamps is pretty unacceptable IMHO.
