The design is OK, but it just needs to be modified a little. The bracket as was installed on my mast was defective. It may be that other brackets are not the same with the tangs behind the web. Please look at the picture attached to the original post and the modified one attached to the first reply. That proves that the design is inadequate or that there is a quality control problem. especially since I pointed out the flaw at the 2001 nationals. If you can improve a part markedly with a simple design change and no added cost of the unit. Why not???
