Frequently Asked Questions
What should I verify for a duct access door?
Verify the duct construction, opening dimensions, access clearance, material, latch, and any gasket or option information shown in the product documentation.
What size access door do I need?
Choose an opening size that provides the access required for the service or equipment, then compare the exact product dimensions and rough-opening guidance in its documentation. Confirm the project opening and access clearance before ordering.
What is the difference between a fire-rated and non-rated access door?
A fire-rated product is identified in its catalog documentation for a rated application; a non-rated product should not be assumed to satisfy that requirement. Confirm the complete assembly, documentation, and project requirements with the architect or authority having jurisdiction.
How should I research alternatives to Acudor or Karp products?
Use the catalog cross-reference fields as a starting point for product research only. Compare the stored public attributes and then verify dimensions, applications, documentation, and project approval; a cross-reference is not an equivalency or approved-substitution claim.
