About Acudor
Acudor was established in 1976 as part of Nelson Industrial Inc., a North American manufacturer of architectural metal products headquartered near Toronto, Canada. Over nearly five decades, Acudor has grown into one of the building industry's leading manufacturers of access doors and related products, with a product line that now spans over 50 models of access doors, 30 floor door models, and 30 roof hatch and smoke vent models, available in hundreds of sizes.
Acudor specializes in access solutions for the full range of building assemblies: walls, ceilings, floors, and roofs, in both fire-rated and non-rated configurations. Their products are used in commercial office buildings, healthcare facilities, schools, hotels, multi-family residential properties, and institutional buildings wherever hidden access to in-wall or above-ceiling systems is required. More than 20% of Acudor's output is custom fabrication, which sets them apart from manufacturers that focus only on standard sizes.

Frequently Asked Questions About Acudor Products
What is the difference between a fire-rated and non-rated access door?
A non-rated access door provides simple concealed access to in-wall systems and is used in non-fire-rated assemblies. A fire-rated access door is UL-labeled to maintain the fire-resistance rating of the wall or ceiling assembly it is installed in. If the wall is fire-rated, the access door must be fire-rated as well. For assemblies that also require temperature-rise control, the insulated fire-rated door is the correct specification.Do I need a stainless steel access door or is a standard steel door sufficient?
Standard galvanized steel doors are appropriate for most dry interior locations. Stainless steel is required in wet locations, commercial kitchens, food processing facilities, and healthcare environments where the door will be exposed to moisture, cleaning chemicals, or steam. Stainless steel also meets the hygiene requirements in settings where surface contamination is a concern.Can Acudor access doors be used in tile walls or masonry?
Yes. The universal flush-mounted metal access doors are designed for installation in drywall, plaster, masonry, tile, and other flush surface materials. The galvanized steel frame accommodates a range of substrate types, making them appropriate for tiled mechanical rooms, masonry corridors, and similar applications.How do I select the right size access door for my project?
Access door size is determined by what needs to be accessed behind the wall or ceiling. The opening needs to be large enough to allow a hand or arm to reach controls, valves, or panels comfortably, with some clearance beyond the equipment itself. Acudor offers doors in a range of standard sizes, and custom sizes are available for non-standard applications.If you are unsure which size fits your project, contact our team and we can help.
