MTLPC	Brite metallic: Custom powder coat fi nish, which resembles that of US26 or US26D plated fi nish.
SRI	For installations where a higher level of protection against weather conditions, or the effects of a potentially corrosive atmosphere is required, LCN offers a special rust inhibiting (SRI) process. Ferrous metal components receive an SRI pretreatment and a standard powder coat fi nish of your choice, or a custom powder coat fi nish for a nominal additional cost. Closers treated with the SRI process exceed the 100 hour protection level available with standard LCN powder coated fi nishes.
