The ALPS Smart Seal Locking Liner (Above Knee) features raised bands that grip the socket wall to form a secure interface. The low modulus bands stretch against the socket wall, while the smooth inner wall conforms easily to the residual limb.

• Material & Build: Formulated with high-density (HD) gel and a seamless knitted outer covering that limits vertical stretch.
• Suspension System: Combines a locking pin attachment with silicone-coated sealing bands that grip the socket wall to create a non-constrictive hypobaric suspension.
• Distal Construction: Features an updated distal design to control distal distraction (pulling/stretching away from the limb). Transfemoral (SA) rings begin 4.95 inches from the center of the distal end.
• Thickness Options: Available in uniform 3mm or 6mm thicknesses.
• Activity Level: Engineered for activity levels ranging from K1 to K4.
• Benefits: Provides rotational control, minimizes pistoning, and reduces localized pressure on the residual limb
