PDQ GP148 Grade 2 Classroom Cylindrical Lever Lock

PDQ GP148 Grade 2 Classroom Cylindrical Lever Lock

Grade 2 Heavy Duty Commercial Cylindrical Lever Lock

The PDQ GP148 is the Classroom function (ANSI/BHMA F84) of the PDQ GP Series Grade 2 Heavy Duty Cylindrical Lock.

The PDQ GP Series is an ANSI/BHMA A156.2 Grade 2 cylindrical lever lock with a heavy duty diecast chassis. Its lever torque resistance of 1,500 lbf-in is tested to three times the ANSI/BHMA standard.

The GP Series complements PDQ's Grade 1 GT and XGT cylindrical locks, using the same Philadelphia, Boston and Miami lever designs and rose options. That lets a building put Grade 1 hardware on exterior and high-traffic doors and GP locks on low to medium traffic openings without a visual mismatch. GP locks are assembled in Lancaster, PA and carry an 8-year limited warranty.

Frequently Asked Questions

What is the difference between the GP and PDQ's Grade 1 GT lock?
GP is Grade 2, rated for lower-traffic openings, while GT is Grade 1 for heavy-duty use. GP shares the same Philadelphia, Boston and Miami lever designs as GT, so a project can specify GT on exterior and high-traffic doors and GP on interior doors without a visual mismatch.

Is the GP lock fire rated and ADA compliant?
Yes. GP is UL listed for 3-hour fire doors on single doors up to 4'0" x 8'0" and complies with ADA and ICC/ANSI 117.1 accessibility standards.

What door prep and backset does the GP use?
GP is a thru-bolt design that fits standard 160/161 door prep on doors 1-3/8" to 1-3/4" thick, with a 2-3/4" standard or 2-3/8" backset.
