Frequently Asked Questions
Is the SV knob lock ADA compliant?
No. Its round ball knob design does not meet ADA/ICC A117.1 operable-parts requirements for hardware usable without tight grasping or twisting, so it should be limited to applications where knob hardware is code-permitted.
What is the difference between the SV and the SX?
Both are PDQ ball knob cylindrical locks. The SV is Grade 2 certified and is the lower-traffic option, while the SX is Grade 1 for high-traffic doors.
What door prep does the SV fit?
The SV fits standard 161 door prep on doors 1-3/8" to 1-3/4" thick with a 2-3/4" or 2-3/8" backset, which makes it a straightforward retrofit for existing knob locksets.

PDQ SV205CQ630 – Frequently Asked Questions
1) What does the double dummy function on the PDQ SV205 actually do?
Nothing mechanical. The SV205 is the double dummy function of the PDQ SV Series ball knob cylindrical lock, which means a fixed knob on each side with no latch, no cylinder and no turning action. It's pull/push trim only, used on inactive leaves of a pair, closet and cabinet doors, or anywhere you want matching knob trim without a working latch. If the door needs to stay shut, you need a separate catch, roller latch or flush bolts, ordered apart from this.
2) Does the PDQ SV205 dummy knob fit standard 161 door prep?
The SV Series fits standard 161 door prep on doors 1-3/8 inch to 1-3/4 inch thick, so it mounts in the same bore as the knob lockset you're pulling off. Because the SV205 is a dummy, there's no latch run to the door edge, so the 2-3/8 or 2-3/4 inch edge bore and the existing strike in the frame are irrelevant to it.
3) Can I use the SV205 dummy on the inactive leaf of a pair of doors?
That's the usual job for it. Put the SV205 double dummy on the inactive leaf so the trim matches the active leaf, and secure the leaf itself with flush bolts or a top and bottom bolt set. The dummy contributes no latching of its own, and it's non-handed, so the same unit works on either leaf regardless of swing.
4) Is a knob lock like the PDQ SV205 ADA compliant?
No. The round ball knob design does not meet ADA/ICC A117.1 operable-parts requirements for hardware usable without tight grasping or twisting. Use it only where knob hardware is code-permitted. For accessible openings you want a lever trim instead. Note that a dummy knob on an inactive leaf is often outside the operable-parts requirement anyway, but the active leaf hardware still has to comply.
5) Is the PDQ SV Series rated for fire doors?
The SV Series is UL/cUL 10C listed for 3-hour fire doors on single doors up to 4'0" x 8'0". It's also ANSI/BHMA A156.2 Grade 2 certified. Keep in mind that a double dummy adds no latching, and a fire door assembly has to positive latch, so the SV205 belongs on an inactive leaf with listed flush bolts or on a non-rated opening, not as the sole hardware on a rated single door.
6) Will the SV205 dummy knob match the keyed PDQ SV knob locks on my other doors?
Yes, it's the same SV Series ball knob trim: stainless steel or wrought brass knobs on 3 inch diameter wrought roses. Order the SV205 in the same finish as the keyed and passage SV functions on the rest of the openings (605 bright brass, 613E dark oxidized satin bronze, or 630 satin stainless steel) and the trim reads identically across the building.
7) Should I buy the PDQ SV or the SX knob lock for a high traffic door?
The SX. Both are PDQ ball knob cylindrical locks, but the SV is Grade 2 standard duty and the lower-traffic option, while the SX is Grade 1 for high-traffic openings. For a dummy trim specifically, traffic matters less since nothing cycles, but if the rest of the openings on the job are SX Grade 1, match the trim family and finish with the SX dummy so the knobs and roses look the same.
8) Do I need to specify a keyway or cylinder when ordering the SV205?
No. The SV205 is the non-keyed double dummy function, so there is no cylinder, no keyway and no keys involved. All you specify is the finish, with the knob style being ball knob (CQ): for example SV205CQ630 in satin stainless. Keyway and keying choices only apply to the keyed SV functions.
9) Does a dummy knob come with a latch and strike?
No latch and no strike with the SV205, because a double dummy has nothing to latch. The 1/2 inch throw solid brass latchbolt and ASA 4-7/8 x 1-1/4 inch strike listed for the SV Series belong to the latching functions, not the dummy. If the leaf has to be held closed, budget separately for flush bolts, a roller latch or a magnetic catch.
10) Will the SV205 dummy work on a 1-3/8 inch wood interior door?
Yes. The SV Series covers 1-3/8 inch through 1-3/4 inch door thickness with standard 161 prep, so it handles both the thinner older interior doors and standard 1-3/4 inch commercial leaves. The knob is non-handed, so one part number works on either swing.
11) Is the PDQ SV205 TAA compliant for a government job?
Yes, the SV Series is TAA compliant, country of origin Korea, which is what a federal or GSA-funded procurement typically needs to see. It's also ANSI/BHMA A156.2 Grade 2 certified for commercial use.
