The ALPS™ Smart Seal Locking Liner features raised bands that grip the socket wall to form a secure interface. The bands stretch against the socket wall, while the smooth inner wall conforms easily to the residual limb. The Smart Seal Liner has a new seamless knitted construction with a modern look and is available in locking and cushion suspension. The locking version features a new distal construction to control distal distraction.

Transfemoral (SA) rings begin 4.95 inches from the center of the distal end.

The liner comes in a variety of sizes and either 3mm or 6mm gel thickness. Your prosthetist has most likely picked out the liner that works best for you. Find the product number on your package to determine what manufacturer number to use.

If you don't have the manufacturer number, you can measure your residual limb and select the number from the chart below.
