Heavy-duty, yet compact, die cast throw off in a classic style is a great upgrade to a standard snare strainer throw off. Very solid, small strainer. Has fairly standard mounting holes that fit many snare drums. This part goes onto the side of a snare drum , and is used to anchor the snare wires on the bottom drum head. They work with a Butt plate on the opposite side of the drum Mounting Screws ARE included.
