Detail 01
Inverted screw placement
The tightening screw sits under the mouthpiece instead of on top, so nothing contacts the reed's upper surface where it vibrates.

Ultimate LigatureFrancois Louis Saxophone Ligatures SAB - Fits Metal Alto Sax Mouthpieces
Independent shopping perspective
The Korena take
Francois Louis SAB ligature for metal alto sax mouthpieces, with inverted screw placement. A deliberate upgrade purchase, not a replacement part.
Strong match
Who this is for
- Alto players on a metal mouthpiece wanting a ligature upgrade
- Players who prefer the screw underneath rather than on top
- Anyone replacing a ligature that never clamped a metal piece evenly
Consider the trade-offs
When to look elsewhere
- Hard rubber alto mouthpieces — the diameter is different
- Soprano or tenor players; this is alto-sized
- Players on a tight budget who just need a working ligature
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
Fits metal alto mouthpieces
Metal alto pieces are slimmer than hard rubber at the same facing. A hard rubber ligature will not tighten down far enough on metal.
Detail 03
Alto-specific sizing
Not interchangeable across the sax family. Soprano is too small and tenor too large for this band.
Detail 04
No cap included
Unlike ligature-and-cap sets, this is the ligature alone. If you need a cap, budget for it separately.
Detail 05
$112.70
Roughly four times entry-ligature pricing. This is bought for the design and fit, not as a spare.
Final check
Know before you order
- 01Confirm your alto mouthpiece is metal, not hard rubber, before ordering
- 02No cap is included — this is the ligature only
- 03Inverted screws change how you seat the reed; give yourself a session to adjust
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does this fit a hard rubber alto mouthpiece?
No. It is sized for metal alto mouthpieces, which are slimmer. On hard rubber it will not close far enough to hold the reed.
02What does inverted screw placement mean?
The screw is on the underside, beneath the reed, instead of on top of the mouthpiece. Nothing sits on the reed's vibrating surface.
03Is a cap included?
No. This is the ligature by itself. Order a cap separately if you need one for reed protection.
04Will it fit my tenor?
No. This is the alto version. Tenor mouthpieces are larger and need the tenor-sized ligature.
