GapCap Saxophone End Cap - A perfect fit for any alto or tenor sax
Don't risk your alto sax or tenor 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.
PROTECT
Flex cap design allows screw to shock absorb impact that can bend your saxophone.
EXPAND

VENT

The Saxophonist Magazine raves that GapCap is “Ingenious... Such a useful tool for so many sax players!”

The GapCap arrived 3 weeks ago, earlier than expected, which seems to happen a fair amount of the time with Amazon Prime! It is easy to use, while a simply devise, it works better than the standard cap that came with my Selmer Reference - Alto Saxaphone; and is a good fit in the case. The added security it provides is worth the money!

I had bought one of these Gap Caps for my tenor and decided to get one for my alto as well. The alto one really fills in the gap for my 1963 Buffet SDA in a Protec case. Great device.

Simply put, the ideal gadget to secure your precious cargo (saxophone) in it's carrying case. This is a small yet mighty little tool vs. the Muppet tubular closure. Great idea for a gift ðŸŽ

This is a great product because when using a third party gig back sometimes the saxophone will move around in the bag causing leaks. This will keep the saxophone from moving, and prevent some trips to the shop. I have one in all my Alto and Tenor bags.

This thing ROCKS. My horn didn't quite fit in the case. The neck was just a bit too short for the case. The Gap Cap adjusts and makes my sax fit precisely in the case. PLUS it is vented which helps the sax dry out better. No sticky keys anymore. Love this thing. Highly recommended.

A great replacement for the cap that comes with your instrument. Helps facilitate air movement through the instrument. It also has an adjustable top to fit in the case.

While expensive, these are terrific plugs. I love their universalness and the extending design that allows the use of multiple cases. This is a huge benefit for those of us who travel on planes and use different cases locally and for travel.

Ideal if your saxophone is a bit too small for the case. It seems to be very well made and does as it is intended. It is fairly pricey, but as does make the saxophone better protected, I think it’s worth the price.

Der Herzschoner ist praktisch, weil dadurch das Sax schneller trocknen kann. Allerdings ist das Material schlecht. Schon nach wenigen Monaten ist der Herzschoner zerbrochen und Garantie gibts nur für 1 Jahr.

Universal fit ( I have a Selmer pro horn) Holes to allow air flow, looks good. Feels like it will last for ever and seems to be very well built. A quality product that is a minor investment to help protect your big investment! There’s always some play in cases and this helps you dial that it so there is no play and your sax is held in place very well.
