The TY-50E from Sirui is a basic, Arca-type compatible, aluminum quick release plate which is offered as the standard plate for Sirui E-10 and E-20 ball heads. The plate features a basic Arca-Swiss dovetail design which allows it to fit most Arca-type compatible clamps, tripod, and monopod heads. Sirui has also equipped this plate with its standard safety lock design, which prevents the plate from accidentally detaching when properly used with Sirui safety-lock heads. Anti-friction rubber mats have also been added to the plate to prevent unwanted camera shift when adjusting the position of your tripod or monopod head.
