The submittal proposes a different manufacturer or product than the spec names, without an approved or-equal or substitution request. This guide covers how it shows up specifically in Division 08 Openings submittals.
What to look for in Division 08 Openings
Div 08 specs name door, frame, hardware, and glazing system manufacturers. Look for:
- Door manufacturer substitutions (Steelcraft/Allegion, Ceco/ASSA ABLOY, Republic Doors, Mesker)
- Wood door manufacturer substitutions (VT Industries, Masonite Architectural, Marshfield, Oshkosh)
- Hardware manufacturer substitutions (Schlage/Allegion, Sargent/ASSA ABLOY, Hager, Best/dormakaba)
- Closer manufacturer substitutions (LCN, Norton, dormakaba, SARGENT)
- Exit device manufacturer substitutions (Von Duprin, Precision, Sargent)
- Aluminum entrance/storefront manufacturer substitutions (Kawneer/Arconic, YKK AP, Tubelite, Oldcastle/C.R. Laurence)
- Curtain wall manufacturer substitutions (Kawneer, YKK AP, Wausau, Vitro Architectural Glass)
- Glass manufacturer substitutions (Viracon, Oldcastle, Guardian, PPG, AGC)
- Overhead door manufacturer substitutions (Overhead Door Corp, Wayne Dalton, Amarr, Cookson)
How severe is it?
Default grade: Blocker. Drops to a Note if the submittal attaches an or-equal approval letter from the architect of record.
Deviation Check assigns a default per category and escalates or de-escalates based on the spec, always showing its reasoning. See the Division 08 severity rules.
What the PM should do
Treat this as a hold. Do not approve the submittal until the sub resolves it, either by providing the specified product and documentation or by routing an approved substitution or or-equal request. Return the relevant spec passage to the sub as a redline.

Frequently asked questions
Which door and hardware manufacturers are commonly substituted in Division 08 Openings submittals?
Common substitutions include steel door manufacturers like Steelcraft, Ceco, Republic Doors, and Mesker, and hardware manufacturers like Schlage, Sargent, Hager, and Best. Exit devices frequently see Von Duprin swapped for Precision or Sargent. Storefront and curtain wall subs often replace Kawneer or YKK AP with Tubelite or Oldcastle. Any of these require an or-equal approval letter from the architect of record to clear the Blocker flag.
How does a subcontractor clear a manufacturer substitution flag on a Division 08 Openings submittal without respecifying every opening?
An or-equal approval letter signed by the architect of record is the single document that drops a Blocker to a Note. The letter must address the proposed manufacturer - for example, YKK AP in place of Kawneer - and confirm equivalency for the applicable performance criteria. Without it, every opening tied to that substituted manufacturer remains blocked regardless of how many cut sheets are included.
