Snareweight Pro-Lock for Die Cast Hoops

From Snareweight:

Pro-lock is used to anchor Snareweight #3 to non-metal hoops like die-cast. Made of solid brass. Pro-lock incorporates an arched magnet to attract to the magnet of the Snareweight #3 through the die-cast hoop. It has a slot that Snareweight #3 drops into, then creates a floating lock to secure damper.

"Snareweight #3" with a "Pro Lock" is as good as it gets for dampening and road worthy durability.Because of the lock between the two magnets, with every drum hit it will reset itself and fall back into place with perfect contact to the head- making it impossible to unhinge itself from the hoop unlike other hardware methods.
