I just learned about the SmallRig HawkLock H18 Quick Release Support with Cold Shoe, Dual-Direction QR-Slide Cold Shoe Mount with Anti–Drop Pin & Silicone Pad and instantly ordered two for my Hummer Rig. They can hold up 1.8lb and are designed for heavy items like LED Video Light, and Microphone so I thought they could easily support the Profoto A10. They do and truly make operations just that much simpler. The sweetest part is they are only $19! If you’ve checked out the prices of cold shoes, you know this is a steal! You have two pieces, one attaches to the flash/LED light/Microphone/etc foot and the bottom piece to a stand, bracket, arm, etc. You the simply slip the accessory into the bottom foot where it locks into place. The simple push of the lever and it’s out. Love these, and ordered more, you might wanna check them out.
