The Cendrex Difference

From the very beginning, in the 1980s, when the company was founded to respond to a growing opportunity for manufacturing ashtrays for building exteriors, Cendrex has been fueled by innovation and vision. Finding great success in this initial venture, Cendrex expanded operations to include producing high-quality access panels, access doors, and mailboxes. Since then, Cendrex has pursued growth through diversification and developing new markets.

Today, thanks to an extensive network of distributors, Cendrex serves companies and distributors in the construction and renovation sector, primarily in North America. Cendrex continues to be known as a leading supplier of exceptional access products including plumbing trap doors, roof hatches, floor hatches, stainless steel access doors, attic access panels, fire rated access panels, and more.
