Stanley Security QRT370 E 690 LC – Frequently Asked Questions

1) Does the Stanley QRT370 exit trim come with a cylinder?
No. The QRT370 ships less cylinder (LC), so you supply the cylinder yourself. It takes a conventional cylinder, not an interchangeable core, so plan on a conventional mortise-style cylinder in a finish that matches the trim. The upside is you can key it into an existing system or swap the cylinder later without pulling the trim off the door.
2) If I need access control or mobile credentials on an exit device instead of a keyed lever, what should I use in place of the QRT370?
Consider the Schlage XE360EW22S, a Grade 1 wireless exit trim with a Bluetooth and NFC mobile reader, an interior pushbutton with LED indicator, for 1-3/4 inch doors and built for the Von Duprin 22 SVR device in classroom/storeroom function. The Stanley QRT370 is a mechanical night latch lever trim supplied less cylinder, so it has no reader or electronics and is designed to pair with Stanley QED300 series exit devices.
3) What is the difference between the Stanley QRT370 exit trim and the Schlage CO-100 exit device trim?
The Stanley QRT370 is a mechanical Grade 1 round rose exit trim with a night latch lever, supplied less cylinder so you install your own conventional cylinder. The Schlage CO-100-993M-70-KP is a Grade 1 standalone electronic mortise exit device trim with an integrated keypad reader, in classroom/storeroom function for 1-3/4 inch doors. The QRT370 is keyed entry by cylinder; the CO-100 is credential entry by keypad with onboard access control.
4) What does night latch function mean on this exit trim, and will it let people in?
Night latch means the lever is always rigid and the key is what retracts the latch. Turn the key and the lever lets you in; let it go and the door is secure again from the outside. Free egress is always available from the inside through the exit device. If you want a lever that stays unlocked until you key it off, a night latch is the wrong function for that opening.
5) Is the QRT370 trim heavy duty enough for a school or hospital corridor?
It is Grade 1, commercial rated trim, which is the top ANSI/BHMA durability tier for door hardware and what is normally specified for schools, hospitals and other high traffic institutional openings. The trim body and rose are brass or bronze alloy.
6) Can I use the QRT370 as a classroom or storeroom lever on a regular door?
No. This is trim for an exit device, not a cylindrical or mortise lockset, so it mounts to the outside of a door already fitted with a Stanley QED300 device and has no latch of its own. For a standalone classroom or storeroom opening you need an actual lockset, not exit trim.
7) I need a storeroom function exit trim rather than a night latch lever - is the QRT370 the right choice?
The QRT370 is a night latch lever trim, meaning the lever is always inactive and the key retracts the latch for entry. If the opening calls for classroom/storeroom function, the Schlage CO-100-993M-70-KP and the Schlage XE360EW22S are both Grade 1 trims listed in classroom/storeroom function for 1-3/4 inch doors, though both are electronic rather than key-only.
8) Do I need to specify handing when ordering the QRT370 exit trim?
The two choices you make on the order are lever design, E Sierra or M Summit, and finish in 626, 689 or 690. Because it ships less cylinder, the cylinder is a separate line item and needs to match your keyway and keying schedule.
