The history of Advantage Lites & Louvers begins in
1938 with the founding of Leslie Welding Company in Chicago, Illinois, a
small specialty welding company, also involved in making miscellaneous
metal ventilation products.
Locke Manufacturing was founded in the 1950’s as a producer of ornamental
iron railing and columns, and quickly became a leader in this industry,
with the majority of its sales through distributors.
In 1967 Locke Manufacturing merged with Leslie Building Products Company,
and Leslie Locke Building Products was formed manufacturing door
accessories, ductwork, ventilation and ornamental iron products. Following
its purchase of Leslie Locke Building Products in 1998, GAF Materials
Corporation operated the company as a division called LL Building Products
At the end of 2004, ZERO INTERNATIONAL acquired the Door Louvers and
Vision Lites product line from LLBP and created Advantage Lites & Louvers.
ZERO continues manufacture of the product line in Burgaw, North Carolina.
