PDQ I12607 – Frequently Asked Questions
1) What does a PDQ T-turn mortise cylinder actually do, and when would I use one instead of a keyed cylinder?
It replaces the keyed cylinder in a mortise lock with a thumbturn piece, so the function is operated by hand with no key. Typical use is one side of an opening where you want keyed control outside and simple turn operation inside, such as a restroom or a privacy or inside-locking function on a mortise lock. Everything else about the installation is the same as a conventional mortise cylinder, it threads into the same cylinder hole.
2) Which cylinder lengths does the PDQ T-turn mortise cylinder come in, and does the length include the cam?
Two lengths, 1-1/8 inch and 1-1/4 inch, and the stated length includes the cam. That matters when you measure what is already in the door: measure the existing cylinder with its cam attached and match it, otherwise the turn will sit proud of the trim or fall short of the lock case.
3) Does the T-turn mortise cylinder have a handing?
Handing only comes into play on the MJ134 function. PDQ makes dedicated right hand and left hand 1-1/4 inch T-turn cylinders in 630 finish for the PDQ MJ Series MJ134. For general mortise applications the standard 1-1/8 inch and 1-1/4 inch T-turns are not handed.
4) I am replacing a broken thumbturn in a mortise lock. How do I pick between the 1-1/8 inch and 1-1/4 inch T-turn?
Pull the old cylinder and measure it from the face of the cam to the outside shoulder, since PDQ quotes the T-turn length with the cam included. Doors with thicker trim or a thicker leaf generally take the 1-1/4 inch; thinner setups take the 1-1/8 inch. If the opening is a PDQ MJ Series MJ134, you need the handed 1-1/4 inch version in 630 finish rather than one of the standard finishes.
5) What finishes can I get a PDQ T-turn mortise cylinder in, and will they match my existing PDQ mortise cylinders?
Seven finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze, 622 flat black, 625 bright chrome, and 626 satin chrome. PDQ lists these as matching their conventional mortise cylinder finishes, so a T-turn ordered in the same number will match the keyed cylinders already on your openings. All seven are offered in both the 1-1/8 inch and 1-1/4 inch lengths.
6) What part number do I order for a 1-1/4 inch T-turn in satin chrome?
I22607. PDQ gives each length and finish combination its own number: the 1-1/8 inch run is I1260x (for example I12605 in 605 bright brass, I12607 satin chrome, I1260H flat black) and the 1-1/4 inch run is I2260x (I22605 bright brass, I22607 satin chrome, I2260H flat black). Specify length and finish together when ordering.
7) Can I key a T-turn cylinder into my master key system?
No. There is no keyway and no cylinder plug to pin, the turn piece operates it by hand. If you need the inside of that opening to be keyed and on the master system, order a conventional PDQ keyed mortise cylinder instead and keep the T-turn for the side you want operated without a key.
8) Is the PDQ T-turn mortise cylinder suitable for commercial doors or is it a residential part?
It is a commercial mortise cylinder, built as a turn-piece substitute for PDQ's keyed mortise cylinders. Property managers standardizing a building can use the same finish numbers across keyed and turn sides so the hardware reads the same on every door.
