This is a replacement battery catch for the Pentax k30, k50, k70 and some other k/kr series Digital cameras. When it brakes and if you rely upon the battery door to keep it in you will put undue stress on door and if the door brakes it WILL be a VERY expensive repair. Here is a replacement battery catch.
NOTICE this is for the replacement catch ONLY, NOT the camera, NOT the lens, NOT the battery, it is for one replacement catch ONLY!!
 A installation hint sheet is supplied with the catch
