TWIST LOCK PRESCRIPTION INSERT

The prescription insert only fits the WX VAPOR 2.5, WX VAPOR COMM 2.5 and SPEAR. However, for the SPEAR you will also need prescription post (SP29PSTTL) for the prescription insert, as it cannot be mounted without one. You can also purchase the prescription insert and post together (SP29XTL)
