Forearm and underarm crutches have different upper sections and adjustment points. This checklist compares two current Max Mobility Alpha models so you can check the specified size, user limit and replacement parts before ordering.
Use it alongside advice from the professional fitting your crutches. It does not decide which design is suitable for an injury or replace fitting, walking or weight-bearing instructions.
Start with the recommended design
The Alpha aluminium forearm crutches have a hand grip and an upper cuff section. The Alpha aluminium underarm crutches have a padded upper section and a separately adjustable hand grip.
Do not choose a design solely because it looks lighter or costs less. Confirm the type, size and fitting requirements with the professional advising you.
Compare the adjustment points
Alpha forearm crutches
Quintro lists two adjustable sections: floor to hand grip, and hand grip to arm cuff. The aluminium model comes in Youth, Adult and Tall options, with rubber tips and dual silencers.
The supplier lists these measurements:
- Youth: user height 137–157 cm; floor to handle 640–870 mm; handle to cuff 270–315 mm.
- Adult: user height 157–177 cm; floor to handle 790–1,020 mm; handle to cuff 270–340 mm.
- Tall: user height 177–198 cm; floor to handle 920–1,160 mm; handle to cuff 270–340 mm.
Alpha underarm crutches
This aluminium model has push-button height adjustment and a hand grip that adjusts separately. Quintro lists Youth for user heights of 137–157 cm, Adult for 157–177 cm, and Tall for 177–198 cm.
Height bands are a starting point, not a complete fitting assessment. Check both the chosen variant and the measurements required for your setup.
Check the exact user-weight limit
Quintro currently lists a maximum user weight of 150 kg for the Alpha forearm model and 120 kg for the Alpha underarm model. These are model-specific limits. Do not transfer a limit from one crutch listing to another.
Confirm the selected product's current specification before purchase. If a label, brochure and listing disagree, ask us to clarify before ordering.
Plan replacement parts by fit
Replacement tips, grips and underarm pads serve different purposes. Check the shaft diameter, part shape and stated model compatibility rather than buying by appearance alone.
The underarm model has replaceable tips, hand grips and upper pads. Browse Parts & Accessories when a component needs replacing, and confirm the correct fit before adding it to your order.
Five checks before buying

- Choose the correct size variant and compare its adjustment measurements.
- Check the exact model's user-weight limit.
