GapCap® is THE ULTIMATE SAX CARE CAP and won the "Outstanding Product" designation from The Saxophonist Magazine.

Don't risk your saxophone with loose fitting end plugs, end caps and sax cases. GapCap® flexes to fit your sax perfectly, screw adjusts to fit your case, shock absorbs impact, and vents air through the top and side for a cleaner saxophone and longer pad life.

Spring wall design flexes to fit the neck socket of all saxophone brands.

Flex spring wall serves as a shock absorber to decrease impact that can break your sax.

Instantly fix a loose fitting sax case by expanding the GapCap® screw, securing your horn to help prevent bent keys, a bent sax body, and costly repair.

Use the optional Lock Nut included to hold your favorite position.

GapCap® vents through the center and side to allow massive airflow into the saxophone body tube. A proven way to keep the saxophone cleaner and help pads last longer. 

Ditch your old sax end plug and go with a GapCap® to flex, expand, vent and protect your saxophone.

• Flex wall spring fits the sax perfectly
