Grover-TrophyTR9400 Flip Folder With 5 Double-Sided Windows
Independent shopping perspective
The Korena take
A marching flip folder with five double-sided windows, holding ten pages of music. For band students who need charts readable while moving.
Strong match
Who this is for
- Marching band students carrying drill music on the field
- Pep band and stand tunes that change every few minutes
- Street parades where loose sheets would blow away
Consider the trade-offs
When to look elsewhere
- Concert players who use a stand and full scores
- Shows needing more than ten pages without reloading
- Oversized or three-ring-punched music that will not fit the windows
What matters in use
The specifications, translated
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 02
Clear plastic windows
Music stays dry and readable in wind and light rain, but glare from stadium lights can wash out a page.
Detail 03
Flip-style pages
You turn with one hand while holding the horn, so the folder stays attached and readable through the turn.
Detail 04
Lyre-mount design
It clips to a lyre on your instrument rather than being held, freeing both hands for playing.
Detail 05
Under five dollars
Cheap enough that a director can outfit a full section, and losing one is not a problem.
Final check
Know before you order
- 01Lyre is not included and is specific to your instrument; buy it separately

- 03Check what lyre mount your school already uses before ordering
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does this include a lyre?
No. The folder holds the music; the lyre attaches it to your instrument. Lyres are instrument-specific, so buy the one that fits your horn.
02How many songs does it hold?
Ten pages across five double-sided windows. That is roughly ten short stand tunes, fewer if any chart runs multiple pages.
03Will standard sheet music fit?
You will usually need to trim or copy music down to the window size. Full-size concert sheets are larger than marching windows.
04Is it waterproof?
The plastic windows keep light rain off the music, but it is not sealed. In heavy rain water can reach the edges of the pages.
