Corbin Russwin TL3720 107T 626 – Frequently Asked Questions

1) Will the Corbin Russwin TL3720 privacy lockset fit a 1-3/8 inch interior door?
Yes. The TL3720 tubular privacy lockset covers doors from 1-3/8 inch (35mm) up to 1-3/4 inch (44mm) as standard, so it works on both older interior doors and standard commercial 1-3/4 inch leaves without any extra kit.
2) What backset does the TL3720 come with, and can I get 2-3/8 inch for an existing door?
Standard backset is 2-3/4 inch (70mm), which is what most commercial preps use. A 2-3/8 inch (60mm) backset is available as an option and has to be called out on the order, so measure from the door edge to the center of the 2-1/8 inch cross bore before you buy.
3) Can I drop a TL3720 into an existing bored door prep?
If the door is already bored to ANSI/BHMA A156.115, yes. The TL3720 uses a 2-1/8 inch cross bore and the door prep conforms to A156.115, so a standard commercial bored-lock prep takes it. Confirm the backset in the existing hole is 2-3/4 inch, or order the 2-3/8 inch option to match.
4) Is the Corbin Russwin TL3720 fire rated for a labeled door?
Fire listing is an option, not standard. UL-cUL fire listing must be specified at time of order for A label and lesser class doors, covering 4 ft x 10 ft single doors or 8 ft x 10 ft pairs. A listed unit carries the letter F and the UL symbol on the armored front, which is how you verify one in the field.
5) What should I use on a closet or hall door instead of the Corbin Russwin TL3720?
The TL3720 is a privacy/bed/bath lock, so it has a locking function meant for bathrooms and bedrooms. On a closet, hall, or any door that never needs to lock, use a passage latch instead - the Schlage PT10 is a non-keyed passage latch in the PT Series with a Passage/Hall/Closet function, which simply retracts the latch from either side with no locking at all.
6) Is the Schlage PT10 a substitute for the Corbin Russwin TL3720 on a bathroom door?
No. The PT10 is a non-keyed passage latch with a Passage/Hall/Closet function, meaning it has no locking mechanism - it will not secure a bathroom or bedroom door. The TL3720 is the privacy/bed/bath function tubular lockset, with the inside locking and outside emergency release that a bath door needs. The two share a tubular format but are not interchangeable by function.
7) Do I have to specify handing on the TL3720, or is it reversible?
Specify the hand of the lock on the order. That said, the TL3720 is field reversible, so if the opening turns out opposite to what was ordered, it can be flipped on site rather than swapped out.
8) What does the privacy function on the TL3720 actually do on a bed or bath door?
It is a Privacy/Bed/Bath function tubular lockset: the inside locks the door for occupancy, and there is no key cylinder on the outside. If you need a door that always stays unlocked, or one that keys, this is the wrong function for that opening.
9) Will the TL3720 latch into a standard strike?
The latchbolt is brass with a 1/2 inch (13mm) projection and ships with a curved lip T-Strike. A 1/2 inch throw is normal for a bored privacy latch, so an existing bored-lock strike prep in the frame will generally accept it, but use the supplied T-Strike if the frame allows, since the curved lip is matched to this latch.
10) Which levers and finishes can I order the TL3720 with?
Three Salvador lever styles, 107T, 110T and 114T, each in 626 Satin Chrome, 630 Satin Stainless Steel, or BSP Black Suede Powder Coat. The trim uses a T Rose design and the lock is built to work with Corbin Russwin Musee levers, so it matches the rest of a Musee-trimmed opening set.
11) I need a passage latch, not a privacy lock, for a closet or hall door. What should I use instead?
The TL3720 locks, so it is not right for a closet or hallway that should always push open. For that, look at the Schlage PT10 passage latch, a Grade 2 non-keyed tubular unit in the PT Series with a Passage/Hall/Closet function, listed for 1-3/4 inch doors.
12) I have doors that are 1-3/8 inch thick - does the Schlage PT10 work there, or do I need the Corbin Russwin TL3720?
The Schlage PT10 lists a door thickness of 1-3/4 inch. The Corbin Russwin TL3720 covers 1-3/8 inch (35mm) through 1-3/4 inch (44mm) as standard, so it is the one to specify when a building mixes thinner interior doors with standard 1-3/4 inch leaves and you want one lock to cover both.
13) Can I standardize a floor of apartments on one tubular prep using the TL3720 and a passage latch?
Yes, that is a common approach. The Corbin Russwin TL3720 uses a 2-1/8 inch cross bore with a 2-3/4 inch backset standard and an optional 2-3/8 inch backset, and the Schlage PT10 is a tubular passage latch for the same style of bored opening. Run the TL3720 at bath and bedroom doors where privacy locking is required and a passage latch at closets and halls, so the door machining stays consistent across the unit.
14) Is the TL3720 heavy-duty enough for apartment turnover and hotel guest rooms?
It is built as a commercial tubular lockset in the TL3700 Series, aimed at interior openings in high-end apartments, condos, hotels, healthcare and schools. For a property manager standardizing bed and bath doors across a building, one lever style and finish across all units keeps the fleet consistent, and the field-reversible latch means the same part number covers both hands.
