I have attached the strap under my battery grip. Has so far everything gefunzt, but when I ahbe still screwed underneath a tripod plate, the grip has always relaxed. Would be super annoying to have to break down every time you still need Propping what. Even repeated tightening by hand has since helped nciht (had no tools at turning this) .... after I pulled the holder so again with pliers bombenfest keeps's now quite well
