Special Rust Inhibitor (SRI) - is a pretreatment that is applied to the metal components prior to the addition of the LCN powder coat finish, standard or custom.  This combination (SRI pretreatment / Powder Coat finish) greatly exceeds the ANSI/BHMA standard A156.4, for corrosion resistance and is for installations requiring a higher level of protection against weathering.

Stronger, smarter and built for the real world.

The LCN 4040XP sets a new standard for reliability, longevity and value with a beefier design and extraordinary performance testing that goes far beyond industry requirements. We built the 4040XP from the inside out, combining tougher, bolder construction with proven LCN technology. The result is a closer that’s stronger, smarter and delivers remarkable value in a variety of applications.
