Demountable bosses are ideal for heavy duty applications and are available for guide posts from 2" in diameter and larger. The bosses are available in three styles. Type 1 is a combination bushing and guide post support. Type 2 is a boss bushing which is flange mounted with the major bearing surface contained within the die set. Type 3 is also classified as a boss-bushing type but with the guide post bearing surface extended below the mounting flange.
