CD40 Arca-Swiss Compatible Back-to-Back QR Clamps
Couldn't load pickup availability
These clamps have fantastic machining and finish. I have Arca-Swiss compatible clamps from other high-end manufacturers. ProMedia Gear clamps are top shelf and at a better price point. These back-to-back clamps are excellent for macro work and also can be separated and used on a ballhead or anywhere a clamp is needed. As usual, with my other ProMeida Gear purchases, customer service was excellent as well.
I bought the pair of QR Clamps to hold a high power laser that weighs about 11lbs. The description of the clamps were spot on and the quality was excellent. Furthermore they feel very strong and I have now concerns about the lasers hold. Great product, thanks!
The quality and function of these machined parts is as good as it gets, no question.
Great quality, works very smoothly and securely. The unit is VERY thin, too, which means it won't add much if anything to the height of stuff attached to my tripod and macro rails. Highly recommended for those who need to attach their lens tripod ring to a rail or other assembly, as well as attaching their camera body through its plate or L-plate. This switch can be made very quickly using this clamp.
