Detail 01
Cap, not a ligature
It covers the reed and ligature. You still need the Ultimate ligature itself for it to sit correctly.

Independent shopping perspective
A replacement cap for Francois Louis Ultimate ligatures, medium size. Buy it if you own that ligature and need a cap that clears it.

Strong match

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
It covers the reed and ligature. You still need the Ultimate ligature itself for it to sit correctly.
Detail 02
Sizing follows the ligature it caps. Match the size you already own rather than the mouthpiece number.
Detail 03
The hardware sits underneath, so the cap is cut to clear a ligature whose screws are on the reed side.
Detail 04
Shaped around the Ultimate ligature's profile. A generic cap usually rocks or won't seat over it.
Detail 05
Cheap enough to keep a spare in the case, which is worth doing since caps are the part that goes missing.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. It's the cap alone, made to fit over Francois Louis Ultimate ligatures. You need to already own the ligature.
It's cut for the Ultimate ligature's shape, not for generic mouthpieces. Expect a poor fit on anything else.
Size matches your existing Ultimate ligature, not your mouthpiece brand or horn. Check the size marked on the ligature you own.
The ligature's tightening screws sit under the mouthpiece rather than on top, and the cap is shaped to clear them.
