Stroboframe Anti-Twist Plate for Canon EOS1 and Nikon N90S Cameras
From Tiffen
Cameras mounted to flash brackets of any brand tend to twist or rotate on the camera mounting screw. Cork or rubber friction pads help, but the real solution is to use a camera-specific Anti-Twist (AT) Plate. These plates act as an interface between the camera and bracket. They pin-register to the bracket and conform to the camera's baseplate. This locks the camera to the bracket to prevent twisting.

Bingo! I should have included this when I bought my Pro-T bracket Bingo! I first got a Stroboframe PRO-T bracket for my Canon EOS 20D with the BGE2 battery extended grip. I mount the camera to the bracket and started shooting. I noticed it twisted no matter how much I tighten the screw on the bottom. I afraid it might messed up my camera screw socket, I bought this Anti-twist 300-BE1. This plate works so well. Now no more twist. No more messed up on my camera socket. Each anti-twist plate works specific to each brand of camera. This one is for Canon EOS cameras. If you have a Nikon, get the one that's fits the Nikon. Highly recommended. Does what it's supposed to do but... I mounted a Canon EOS 40D 10.1MP Digital SLR Camera (Body Only) with Canon BG-E2N Battery Grip for Canon 20D, 30D, 40D & 50D Digital SLR Cameras, a Canon EF 70-200mm f/4 L IS USM Lens for Canon Digital SLR Cameras and a Canon Speedlite 580EX II Flash for Canon EOS Digital SLR Camerason a Stroboframe Pro-T Flash Rotating Bracket. This camera set-up is fairly bulky and heavy. I first used the bracket with the supplied cork attached at the base (without the the anti-twist plate mounted.) I put the bracket to its paces by flipping the bracket extension and shooting a number of pictures at both landscape and portrait orientations. The camera set-up eventually nudged and twisted from the bracket's base. I had to tighten the bracket mounting screw several times as a result. What you don't want is the inconvenience of re-tightening this mounting screw often when the nudging happens in the field. You also want to avoid the posssibility of damaging the battery grip's less sturdy tripod socket from excessive loosening and re-tightening especially if heavy lenses are used. The plate solved the "nudging/twisting" issue as promised. Two small pins at the bottom of the plate together with a small mounting screw ensure that the plate is securely attached to the bracket. The bracket with the heavy camera set-up mounted felt very stable and I did not experience any twisting. The negatives: - You will have to dismount the camera set-up from the bracket to replace the batteries. The plate's top portion blocks the battery compartment door lid. - The plate will scratch the battery grip compartment lid due to frequent mounting and dismounting. Stroboframe recommends the anti-twist plate as an option if you use a camera with an attached battery grip. I disagree. The anti-twist plate is a necessity.
