Facom 1/2" Drive 1000v
Insulated Socket. Sockets should be used with an insulated
ratchet/torque wrench, T-handle or other insulated
driver/extension (from Facom, Cementex or Salisbury) to ensure
adequate protection. This socket (a component of the S.401AVSE set) has been discontinued by Facom....I have 2 left in stock.
