Detail 02
Two plies of film. Shorter sustain, more durability, stands up to hard marching sticking.
Detail 03
A translucent film with a slightly warmer, more focused attack than clear film, without the extra dampening of coating.
Detail 04
Head size must match your drum's shell diameter exactly. A 14 will not stretch onto a 13.
Detail 05
This is the top head you strike, not the bottom resonant head.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. The Crimplock hoop is a marching mounting system and does not seat in a standard drum set counterhoop.
Top. It is a batter head, meant to be struck.
Two plies instead of one. Less sustain and overtone, more durability under heavy playing.
A drum key to loosen and retension the rods. Not included.
