Characteristics of the pins and retainers systems for GETs:

  • The pin body, made of only the highest quality steel, features optimal resistance that allows it to be reused.
  • The retainer is comprised of two components. The first one is Elastomet which provides flexibility and elasticity. The second component is compact polyurethane. The two materials are combined to form a single piece.

The combination of a pliant, elastic pin and a reusable, sturdy body provides excellent flexibility in assembly.  This means maximum versatility as you can use the pin with the tips and adapters that you prefer.
