FAQs
What makes the GT Series PDQ's standard Grade 1 cylindrical lock for commercial doors?
GT is ANSI/BHMA A156.2 Grade 1 certified with 2,200 lbf-in lever torque resistance (three times the ANSI standard), covering everyday commercial exterior and interior openings. It's PDQ's general-purpose Grade 1 workhorse before stepping up to a more extreme-duty option.
Is GT strong enough for a busy school or office building, or do I need to step up to XGT?
GT handles standard-to-heavy commercial traffic and covers the large majority of exterior and interior doors in schools, offices, and retail buildings. Reserve XGT, rated to 3,000 lbf-in of torque resistance, for openings facing extreme abuse or vandalism.
What warranty comes with the GT cylindrical lock?
GT carries a 25-year limited warranty, backed by a heavy-duty diecast chassis, billet steel spindles, and cycle testing to over 3x BHMA standards.
Is the GT lock fire-rated and ADA compliant?
Yes, GT is UL 10C listed for 3-hour fire doors (single doors up to 4' x 8') and complies with ADA and ICC/ANSI 117.1, so it's approved for both fire-rated and accessible egress openings.
What lever styles and finishes are available on the GT Series?
GT ships in three lever designs (Philadelphia, Boston, and Miami), across eight standard finishes (605, 606, 612, 613E, 619, 622, 625, 626), with antimicrobial and weatherized coatings available on 626.
Can GT be used on hurricane-rated openings in Florida?
