What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.

Detail 01
Large enough to pass a standard mic through. Measure your existing hole before ordering, since the ring must match.
Detail 02
It trims and protects an existing cut. It does not make the hole for you.
Detail 03
Cosmetic. Shows against white or black heads. Does not alter tone.
Detail 04
Grips the head edge without adhesive or hardware, so it can be moved to a new head later.
Detail 05
Stops the mylar from tearing outward from the hole under vibration, which is how ported heads usually fail.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. The ring finishes and protects a hole you have already cut. Bass Drum O's sells separate cutters, or you can cut carefully with a heated tool.
The cut needs to match the ring's inner dimension so the ring can grip the head edge. Cut slightly undersized first and trim to fit.
The port itself does. It shortens sustain and lets air escape, giving a punchier, drier note than a fully sealed front head.
Yes. It snaps on rather than gluing, so it comes off and transfers to a new resonant head once you cut a matching hole.
