- The high maximum flexion angle of 150° offers extensive freedom of movement.
- With a maximum body weight of up to 150 kg and an additional threaded connector version for long residual limb fittings, this product will be of interest to a broad group of users.
- Individual adjustment options are clearly explained in the included quick reference guide.

The manual lock integrated into the upper section improves user safety in wet areas and makes standing for extended periods more comfortable. With a load on the forefoot, the lock can be easily activated/deactivated by moving the small lever on the side down/up.
As identified by the logo on the back, the 3R80 has a waterproof design so it can be used in wet areas, for instance in the shower or at the pool.
The available threaded connector enables a better fitting option for users with long transfemoral residual limbs.
Optimal adjustment values for stance phase damping and response behaviour are achieved by gradually turning the adjustment rings.
The 3R80 offers four adjustment options for stance phase and swing phase control. Flexion and extension resistance can be adjusted easily and independently.
