  • Perfect tool to use
Size: Alto Saxophone
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 🎁

  • It’s Great
Size: Alto Saxophone
The GapCap is terrific. I got both alto and tenor versions. My Conn 26M is in a vintage, non-Conn case. There’s a big gap at the top. The GapCap extended far enough to hold the horn tightly. My 10M is in a Gator hard case and the GC snugged up the fit considerably. Works great!

  • GapCap Works as Advertised!
Size: Alto Saxophone
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! ... show more

  • Didn’t perform as expected
Size: Alto Saxophone
My saxophone has just a little bit of play inside of it’s case and I thought this product would remedy that issue. No matter how long or short I adjusted the gap cap, my saxophone just wasn’t getting more snug in the case. This is arguably an expensive piece of equipment and since it didn’t make my sax fit like a glove I decided to return it. Note: I own a Jean Paul AS-400 ... show more

  • Love it
Size: Tenor Saxophone
Worked the way it was intended. My Couf Tenor Sax is more snug in my case. It also lets it breath & dry out.

  • Fits in my case.
Size: Tenor Saxophone
Having tough time to find a end plug fits in my case and this is a perfect one.

  • Tenor and Alto saxophone venting system
Size: Alto Saxophone
Just an excellent product for airing out your saxophone even when stored in its case. This product along with the Key Props sold by the Key Leaves company extend the life of your pads. Now if they would make one for a soprano sax, it would be a home run.

  • GapCap for tenor saxophone
Size: Tenor Saxophone
I really dig this product as the concept for protecting the horn seems to be dead on. I love how I can custom fit it to any case I put the horn in. Easy do use and works great.
