Fitting the Masalo Cuff Correctly: 4 Common Mistakes and How to Fix Them
If the cuff hardly seems to work or keeps slipping, one of four typical mistakes is usually to blame. Here you can see each mistake in a photo comparison – with how to spot it and how to fix it.

Key points at a glance
- The forearm cuff belongs in the middle of the forearm, not at the elbow.
- The upper-arm strap is tight enough that you can only straighten your arm with some effort.
- The upper-arm strap sits just above the elbow bone, not up towards the shoulder.
- Too tight is also wrong: you must still be able to straighten your arm.
Compare your cuff with the photos: the red cross shows the mistake, the green tick the correct fit. You will find the complete procedure in our illustrated fitting guide.
Mistake 1: the forearm cuff is too close to the elbow
- How to spot it: you can straighten your arm without any effort and there is no counter-traction. Often the upper-arm strap slips as well.
- How to fix it: position the forearm cuff halfway between the hand and the elbow and fasten it so that it cannot slide upwards. When you straighten your arm, a bulge will then appear in front of the elbow.

✓Mistake 2: the upper-arm strap is too loose
- How to spot it: the cuff slips, and you can straighten your arm fully without any resistance.
- How to fix it: bend your arm and fasten the upper-arm strap tightly enough that the elastic does not stick out much and the cuff fits snugly against the skin. After that, it should only be possible to straighten your arm with some effort.
✕
✓Mistake 3: the upper-arm strap is too high
- How to spot it: the strap is fastened up towards the shoulder. The arm is restricted in its movement, or the strap slips down after a few movements.
- How to fix it: position the upper-arm strap just above the elbow bone. As a rule of thumb: when your arm is bent at about 90 degrees, the cuff also forms an angle of roughly 90 degrees.
✕
✓Mistake 4: the cuff is adjusted too tightly
- How to spot it: you cannot even begin to straighten your arm, and it stays in a protective position. Circulation may be impaired.
- How to fix it: loosen the upper-arm strap until you can straighten your arm with some effort. A tight setting only makes sense with acute pain or heavy strain such as work or strength training – loosen it again afterwards.

✓Checklist: this is how the cuff should fit
- Forearm cuff halfway between the hand and the elbow
- Marker dot roughly centrally in line with the crook of the elbow
- Upper-arm strap just above the elbow bone, fitting snugly
- Straightening only with some effort, with a visible bulge in front of the elbow
- The arm remains normally mobile, no protective posture
