Each key is heat treated for strength and finished in one of five attractive coatings. A hard coat lacquer is baked on for added protection. The unique ASP BackSet feature allows rapid location of the handcuff keyway.Logo Keys feature distinctive insignias, full color State Seals or custom agency logos.
