For sixty years, Knowles Door Check has handled the door hardware scope that others won’t — the complicated submittals, the spec mismatches, the field calls at 4 p.m. on a Friday. We are the people contractors and glaziers call when the project has to be right.
Most coordination breakdowns happen at the seams between estimating, shipping, and field technical support. Knowles handles all three under one roof — specs that clear review the first pass, hardware boxed by opening for clean installs, and senior techs on call when the job changes after the schedule is locked.
Compatibility review, submittal packages, and hardware schedules prepared by senior estimators with six decades of door-type expertise. First-pass approvals, not back-and-forth revisions.
“Specs that clear review the first pass.”
Phased deliveries, multi-site logistics, and box-by-opening markings built around your install sequence. Hardware arrives ready to hang — not in a pile your foreman has to sort.
“Hardware where it’s needed, when it’s needed.”
Direct line to senior technicians for manufacturer coordination, schedules built from scratch when specs are incomplete, and field support that picks up the phone — not a ticket queue.
“Senior techs on the line, every call.”
Door hardware fails when nobody owns the seams — between architect, fabricator, GC, and the field crew installing on a Friday afternoon. Knowles sits in the middle of that workflow, translating between the four parties so the hardware that arrives matches the openings that exist.
Without a coordinator owning the middle, every revision becomes a four-way phone tree. Architects don’t know what the door manufacturer changed. The GC doesn’t know what the architect specified. The field crew gets hardware that doesn’t match the openings. Knowles is what keeps the message intact across all four parties.
Stadium concourses, federal hospitality, luxury hotels, multifamily, resort entries — the projects below are a sample of the openings Knowles has coordinated. Click any tile to see it full-size.
Specifying Knowles means a single accountable partner from submittal through punch list — no finger-pointing between manufacturers, fabricators, and field crews.
