PDQ XGT177 Grade 1 Patio / Privacy Cylindrical Lever Lock

Grade 1 Extra Heavy Duty Cylindrical Lock

The PDQ XGT177 is the Patio / Privacy function (ANSI/BHMA F77) of the PDQ XGT Series Grade 1 Extra Heavy Duty Cylindrical Lock.

The PDQ XGT Series is an extra heavy duty cylindrical lock certified to ANSI/BHMA A156.2 Grade 1 and cycle tested to over 3 times the BHMA standard. A 2:1 latch bolt throw allows a 41 degree lever rotation with the 2-3/4" backset, which reduces torque and lengthens the life of the lock.

XGT is the step up from the GT Series for doors that face heavy abuse, with 3,000 lbf-in of lever torque resistance and a 13-gauge steel anti-rotation plate. It is assembled in Lancaster, PA.

Frequently Asked Questions

What is the difference between the PDQ XGT and GT cylindrical locks?
Both are ANSI/BHMA Grade 1. XGT is rated for 3,000 lbf-in of lever torque resistance, about 4 times the ANSI/BHMA standard, versus 2,200 lbf-in for GT. XGT also uses a 13-gauge steel anti-rotation plate and is cycle tested to over 3 times BHMA standards.

Is the XGT lock fire rated?
Yes. XGT is UL listed for 3-hour fire doors on single doors up to 4'0" x 8'0", meeting UL 10C requirements.

What door thicknesses and backsets fit the XGT lock?
XGT fits doors 1-3/4" to 2-1/4" thick (preset for 1-3/4") with a 2-3/8" or 2-3/4" backset, and it is non-handed, so one unit installs on any door hand.

PDQ XGT177BSN626 – Frequently Asked Questions

1) What does the PDQ XGT177 patio/privacy function actually do, and is there a key?
The XGT177 is the ANSI/BHMA F77 patio/privacy function: it locks from the inside by push button or turn, with no keyed cylinder at all. The field data lists it as non-keyed, so there is no outside key override. Use it where you want privacy on a restroom, patio or bedroom-type door and nobody needs to get in from the outside with a key. If you need an outside key override, you need a keyed XGT function instead.
2) Will the PDQ XGT177 fit a 2 inch thick door?
Yes. The XGT cylindrical lock covers doors from 1-3/4 inches to 2-1/4 inches thick and ships preset for 1-3/4 inches, so a 2 inch door is inside the range with no special order. It mounts through-bolted into a standard ANSI A156.115 (161) cylindrical prep, which is the common 2-1/8 inch cross-bore prep already in most commercial doors.
3) Do I need to specify a hand when ordering the XGT177 lever lock?
No handing to call out. The XGT177 is non-handed, so one unit installs on a left or right hand door, inswing or outswing. You do pick the lever style (Philadelphia, Boston or Miami) and the finish, but not a hand.
4) Will the XGT177 latch into my existing ASA strike?
The standard setup is an ASA strike at 1-1/4 x 4-7/8 inches, which is the common commercial frame prep, so it drops into an existing ASA cutout. Latch throw is 9/16 inch with the 2-3/4 inch backset and 1/2 inch with the 2-3/8 inch backset. If your frame is prepped differently you can order a T-Strike at 1-1/8 x 2-3/4 inches or a Full Lip Strike at 1-5/8 x 2-1/4 inches instead.
5) Can I use the PDQ XGT177 on a fire rated door?
Yes. The XGT lock is UL 10C listed for 3-hour fire doors on single doors up to 4 ft by 8 ft. Note that the F77 patio/privacy function has no outside key override, so confirm the opening's occupancy and egress requirements allow a privacy function before installing on a rated door.
6) Is the PDQ XGT177 lever ADA compliant for a school or healthcare corridor?
The lever trim complies with ADA and ICC/ANSI 117.1, and the lock is certified to ANSI/BHMA A156.2 Grade 1 at extra heavy duty. The 2:1 latch design gives a 41 degree lever rotation at the 2-3/4 inch backset, which cuts the operating torque a user has to apply.
7) Should I buy the PDQ XGT or the GT cylindrical lock for an abuse-prone door?
Both are Grade 1. Go XGT where the door takes real abuse: it resists 3,000 lbf-in of lever torque versus 2,200 lbf-in on GT, adds a 13-gauge steel anti-rotation plate, and is cycle tested to more than three times BHMA standards. For normal commercial traffic without a vandalism problem, GT is the lighter-spec step down.
8) What extras can I add to a PDQ XGT177 order for a hospital or x-ray room?
Two options matter for healthcare. LL adds a lead-lined rose for x-ray and imaging rooms, and AM adds an antimicrobial coating on the inside and outside levers and roses, available in 626 satin chrome only. A DB dust box for the strike pocket is also available. Tactile abrasive coating can be specified inside only (TC1IS), outside only (TC1OS) or both sides (TC2) for hazardous-door warning.
9) Is the PDQ XGT177 suitable for an exterior door in a Florida coastal building?
The XGT Series carries Florida HVHZ approval under PDQ Product Approval FL 21376, with a design load of plus or minus 70.0 PSF on a 3 ft by 7 ft single door. For exposed exterior use, the weatherized finish option is offered in 626 satin chrome only.
10) Can the XGT177 privacy lever be wired for request-to-exit monitoring?
The REX request-to-exit option is available on the XGT platform, and ISMC adds an industry standard Molex connector for the wiring termination. The lock itself is mechanical, not electronic, so the REX switch only signals lever movement to your access control or monitoring panel; it does not lock or unlock the door electrically.
11) Will the PDQ XGT177 work on a pair of double doors?
Yes, with the right latch. Standard lever rotation is 41 degrees using the 2-3/4 inch backset latch; for double doors the 2-3/4 inch latch arrangement gives 65 degrees of lever rotation, which is what clears the astragal or adjacent leaf. Call that out when you order rather than assuming the standard build.
12) What finishes and lever shapes does the PDQ XGT177 come in?
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. Each is available with the Philadelphia, Boston or Miami lever, all solid diecast on a 3-3/8 inch wrought brass rose with concealed screws. If you need the exterior and interior trim to match two different sets of hardware, the SF split finish option lets you specify the outside trim first, then the inside.
