The retro-fit system allows the snare wires to self-center every time you active the snare throw-off. The self-centering action reduces or eliminates any snare wire buzzing noise that can typically be caused by installing the wires crooked or off-set.
The system comes standard withe 4 screws, 2 end plates, a hex wrench, and 4 cords that will hold 2 snare wires.
Snare wires can be swapped out quickly by unhooking the cord loop on both sides of the drum (no tools required)
This system fits all DW MAG throw-offs and 3P butt plates. The cord loop has to be adjusted to the drum's size and set up the first time by tying the knot.
Using this system, you can have many sizes and styles of snare wires ready to change by setting the cord length the first time and tying a double knot. Once this step is done, you can take off the wires and swap with a different set in less than a minute.
