Alpha® Classic BK Liner

In order to provide an excellent socket fit and maximum comfort, Alpha Classic Liners are available in three gel thicknesses and various profiles. Alpha Classic Liners are composed of a skin-friendly thermoplastic elastomer. The gel flows to adapt to uneven socket pressures, while its low rebound means the liner maintains its adapted shape over time. The liners are heat moldable, allowing prosthetists to easily stretch the liners within their facilities.

The durable Original fabric helps extend the life of the liner. To aid in maximizing socket life, Alpha Classic Liners will retrofit with other Alpha Liners having the same profile, thickness, and umbrella.

Features and benefits:

  • Distinct gel profiles accommodate various transtibial limb shapes
  • Available in Cushion and Locking
  • Available in 3 different fabrics
  • Thermoplastic elastomer gel with mineral oil

Measuring Guide

Ensure accurate measurements at 4cm and 30cm from the distal end to determine the most appropriate liner for the user.
