Good morning, Charles;
Go to www.custombrackets.com I cannot claim that they are perfect, but the Custom Brackets products are well made. I do not like the molded plastic grip on the side, so I took mine off and just use the 3/8 inch thick aluminum for a handle when carrying it. It did take heating the aluminum with a heat gun to get the Loctite to soften and allow the Allen headed screws to back out. It does work well. It also weighs something. My normal working setup with camera and flash mounted comes to seven (7) pounds.
