About Elmdor

In 1989, Elmdor Manufacturing Co. was founded as a division of Acorn Engineering Company, manufacturing stainless steel access doors. A leader in the stainless steel manufacturing space, Elmdor was a reflection of Acron’s success and a new direction for the company to grow.

There is a reason that Elmdor has customers from every market imaginable. They have made their name on quality, service, and inventory, and continue to hold themselves to the highest standard. All of Elmdor’s products are proudly made in North America.

Surfaced Mounted
Surfaced Mounted Valve Boxes provides a fully enclosed access box to valves and controls that may extend outside of the finished wall.

Roof Hatches

Elmdor Stoneman’s Roof Access Hatches are the solution for all commercial applications requiring convenient access to the roofs of buildings.

Roof Access Hatches are constructed of high-grade galvanized steel and feature an automatic arm that holds open the hatch during use.
