Stroboframe 300-Base QRC Base Only (Black)

I've used these successfully for many years. Great for quick change off the tripod. Only limit is that it is marked as being designed to hold no more than 6-1/2 pounds.I notice also that as it's spring loaded to secure the base plate to the QRC clamp, it does not attach the camera to the tripod absolutely tight. It's secure, but you can wiggle the camera a bit against the spring.The spring base body comes with a 1/4-20 threaded hole that mounts to the tripod head or other accessory. The plate in the early days went on the camera in only one direction. These days the plate has been reshaped so no matter how you put it on the camera, it will always fit the base adapter properly.To use it, you cock the base place against its spring by pushing in the latch on the left side. It catches in the open position. Then, when you drop the camera into the base, it releases the spring and clamps shut on the plate with a satisfying "thwunk." To release, press in the latch and lift. Camera comes free and is easy to remove.While there are dozens of different plates out there from many different manufacturers, and if I were just beginning (and hadn't invested so much in these Stroboframe QRC's) a more universal standard quick disconnect plate system seems to be the Arca-Swiss ( Desmond DAC-01 50mm QR Clamp 3/8" w 1/4" Adapter Arca Compatible for Tripod Head ). The basic dimensions and shape of the plate have been adopted by many different manufacturers. You can choose from many options.

This base makes can be used on a Tri-pod or Mono-Pod. Very easy to use. Great quality. Make sure it is secured with the screw.

I love the 300-QRC. It is simple in design and easy to mount and dismount the camera. When you place the camera on the 300-QRC, it latches onto the 300-PLT like stepping on a beartrap. Very secure and reliable.

A timeless classic! I've used these quick releases from Stroboframe for years. Quick and easy to use, and very sturdy and reliable.
