PDQ GT126 Grade 1 Passage Cylindrical Lever Lock
Grade 1 Heavy Duty Commercial Cylindrical Lock
The PDQ GT126 is the Passage function (ANSI/BHMA F75) of the PDQ GT Series Grade 1 Heavy Duty Cylindrical Lock.
The PDQ GT Series is a Grade 1 heavy duty cylindrical lock certified to ANSI/BHMA A156.2. PDQ positions it as its general purpose Grade 1 lock for everyday commercial exterior and interior openings, with lever torque resistance of 2,200 lbf-in, three times the BHMA/ANSI standard, and cycle testing to over 3 times BHMA standards.
A heavy duty diecast chassis, machined billet steel spindles and a 13 gauge steel anti-rotation plate on the secure side give the lock its strength. A 2:1 latchbolt throw allows a 41 degree lever rotation, which reduces torque and extends the life of the lock. The GT is non-handed, assembled in Lancaster, PA, and offered in Philadelphia, Boston and Miami lever styles.

PDQ GT126BSN626 – Frequently Asked Questions
1) Does the PDQ GT126 lever lock have any locking function, or is it always free to turn?
The GT126 is a passage lock, ANSI/BHMA function F75, so it latches the door but never locks. There is no cylinder and no thumbturn, both levers always retract the latch. Use it on corridor, closet and stairwell-side openings where you only need the door held closed. If you need to lock the opening, you need a keyed function in the GT Series instead.
2) Will the PDQ GT126 fit a 2-inch thick door, or only 1-3/4 inch?
It covers 1-3/4 inch through 2-1/4 inch doors and ships preset for 1-3/4 inch, so a 2 inch door is within range, just adjust at install. It mounts with through-door thru-bolting into a standard ANSI A156.115 (161) cylindrical prep, so an existing commercial bored door needs no new drilling.
3) My existing doors are bored at a 2-3/8 inch backset. Can I still use the PDQ GT126?
Yes, backset is an order choice. Standard is 2-3/4 inch with a 2-1/4 x 1-1/8 inch faceplate and a 9/16 inch latchbolt throw; the 2-3/8 inch option comes with a 2-1/4 x 1 inch faceplate and a 1/2 inch throw. Both latches are deadlocking. Pick 238 to match doors already bored at 2-3/8 inch.
4) Will the GT126 latch into the strike plate already in my frame?
Three strikes are offered so you can match what is in the frame: the standard ASA strike at 1-1/4 x 4-7/8 inches, a full lip strike at 1-5/8 x 2-1/4 inches, or a T-strike at 1-1/8 x 2-3/4 inches. With the 2-3/4 inch backset the latch throws 9/16 inch, 1/2 inch with the 2-3/8 inch backset, and the front is beveled 1/8 inch in 2 inches. If the existing frame has an ASA cutout, order the ASA strike and reuse the prep.
5) Can the PDQ GT126 passage lever go on a 3 hour fire rated door?
Yes. The GT Series is UL 10C listed for 3 hour fire doors on single doors up to 4 feet by 8 feet. It is also certified to ANSI/BHMA A156.2 Grade 1 and complies with ADA and ICC/ANSI 117.1, which covers the lever-operation requirement for accessible openings.
6) What is the PDQ GT126 the equivalent of in Schlage or Sargent?
PDQ cross references the GT126 passage function to Best 9KxxN, Corbin CL3310, Dorma C110, Falcon T101, Hager 3410, Marks N, Sargent 10U15, Schlage ND10 and Accentra 5401LN. So if the spec on your drawing calls out an ND10 or a 10U15 passage lever, the GT126 is the PDQ answer for that line item.
7) Do I need to specify left or right hand when ordering the PDQ GT126?
No handing to specify. The GT126 is non-handed, so one lock covers left and right hand openings. That is useful if you are stocking spares for a building with doors swinging both ways.
8) What lever styles and finishes does the PDQ GT126 come in?
Three lever styles, Philadelphia, Boston and Miami, all solid diecast on a 3-3/8 inch diameter wrought brass rose with concealed screws. Seven finishes: 605 bright brass, 606 satin brass, 613E dark oxidized satin bronze, 619 satin nickel, 622 flat black, 625 bright chrome and 626 satin chrome. All three lever styles are offered in all seven finishes, so you can match passage openings to the keyed GT functions elsewhere in the building.
9) Is the PDQ GT126 heavy duty enough for a school corridor, or should I step up to the XGT?
The GT handles standard to heavy commercial traffic with 2,200 lbf-in of lever torque resistance, three times the BHMA/ANSI minimum, plus a diecast chassis and a 13 gauge steel anti-rotation plate. That covers most school, office and retail openings. PDQ reserves the XGT, rated to 3,000 lbf-in, for openings facing extreme abuse or vandalism.
10) What options should I add to a PDQ GT126 order for a hospital or clinic door?
Two matter for healthcare. The lead-lined rose (LL) is for imaging rooms where the wall and door are shielded. The antimicrobial coating (AM) covers inside and outside levers and roses and is available on 626 satin chrome only. Tactile abrasive coating is also offered, inside only (TC1IS), outside only (TC1OS) or both sides (TC2), for hazardous-room identification. A dust box (DB) can be added behind the strike.
11) Can the PDQ GT126 be used on an exterior door in a Florida hurricane zone?
Yes. The GT Series is approved for Florida HVHZ under PDQ Product Approval FL 21376, with a design load of plus or minus 70.0 PSF on a 3 by 7 foot single door. For exposed exterior openings, the weatherized finish option is available on 626 satin chrome.
12) Can a passage lock like the GT126 be monitored for door use on an access control job?
Request to Exit (REX) is an available option on the GT, and an industry standard Molex connector (ISMC) can be specified for the wiring termination. The lock itself is mechanical, not electrified, so REX gives you a signal from the lever rather than electric locking or unlocking.
13) Why does the PDQ GT lever only rotate 41 degrees, and does that change on a pair of doors?
A 2:1 latchbolt throw lets the lever retract the latch in 41 degrees of rotation at the 2-3/4 inch backset, which cuts the torque on the chassis and extends lock life. For double doors using the 2-3/4 inch latch, rotation is 65 degrees.
14) I need two different finishes on the inside and outside of the door. Can the GT126 do that?
Yes, the split finish option (SF) covers it. It is priced at the higher of the two finishes, and when ordering you designate the outside trim first, then the inside.
