Stanley Security QRT371 E 690 LC – Frequently Asked Questions
1) Does the Stanley QRT371 exit trim come with a cylinder?
No. The QRT371 is the Less Cylinder (LC) version, so you order the core separately and match it to whatever keying system the building already runs. Plan on buying a cylinder with the trim, or the opening will not lock from the outside.
2) What does the night latch function on the QRT371 trim actually do at the door?
Night latch means the outside lever is always rigid and pulls the latch only when the cylinder is turned by key. From the inside, the exit device always allows free egress. It suits a service or back entry where staff key in and anyone inside can push out at any time.
3) What can I use instead of the Stanley QRT371 exit trim if I need keypad access rather than a key cylinder?
The Stanley Security QRT371 is a Grade 1 mechanical exit device trim with a night latch lever and no cylinder supplied, so every entry requires a key. If you want credential-based entry on the same opening, the Schlage Electronics CO-100-993M-70-KP is a standalone electronic mortise exit device trim with a keypad reader, also Grade 1, in a classroom/storeroom function for doors 1-3/4 inches thick. That swaps mechanical keying for programmable user codes at the trim.
4) Is there a Grade 1 exit trim that works with a mobile credential instead of a key?
The Stanley Security QRT371 is a Grade 1 round rose night latch lever trim that takes a cylinder you supply, so it is keyed only. For mobile credentials, the Schlage Electronics XE360EW22S is a Grade 1 wireless exit trim with a Bluetooth and NFC mobile reader plus an interior pushbutton LED indicator, built for the Von Duprin 22 SVR device and 1-3/4 inch doors. The QRT371, by contrast, is designed to pair with Stanley's QED300 exit device series.
5) Can I put the Schlage XE360EW22S trim on a Stanley QED300 exit device in place of the QRT371?
No. The Stanley Security QRT371 is built to pair with Stanley's QED300 exit device series, while the Schlage Electronics XE360EW22S is specified for the Von Duprin 22 SVR device. They are not interchangeable trims on the same chassis, so stay with the QRT371 for a QED300 opening unless you are also changing the exit device.
6) Do I have to specify handing when ordering the QRT371 lever trim?
No handing to call out. The QRT371 is non-handed reversible lever trim, so one part covers left and right hand openings. What you do specify is finish and lever design.
7) What lever styles and finishes can I get the QRT371 exit trim in?
Two lever designs, E Sierra and M Summit, each available in 626 satin chrome, 689 aluminum, and 690 painted duranodic bronze. Six combinations total. Pick the finish that matches the exit device already on the opening.
8) Is the QRT371 trim heavy enough for a school or high traffic commercial entry?
It is a Grade 1 commercial trim with a brass/bronze alloy body, which is the top ANSI/BHMA durability tier used on institutional openings. That is the right level for corridor and exterior doors in schools, healthcare, and multi-family.
9) What type of cylinder core does the QRT371 take?
The trim is catalogued with a conventional cylinder classification, so order a conventional mortise cylinder to suit, keyed to your existing system. Nothing about the trim restricts you to one keyway, which is the point of buying it less cylinder.
10) What is the difference between the Schlage CO-100 and XE360EW22S exit trims if the Stanley QRT371 will not cover my access control needs?
Both are Grade 1 and fit 1-3/4 inch doors. The Schlage CO-100-993M-70-KP is a standalone electronic mortise exit device trim with a keypad reader in a classroom/storeroom function, so codes are managed at the door. The XE360EW22S is a wireless exit trim with a Bluetooth and NFC mobile reader and an interior pushbutton LED indicator, matched to the Von Duprin 22 SVR device. The Stanley QRT371 remains the mechanical option, a round rose night latch lever trim supplied less cylinder.
11) Can the QRT371 be used for a classroom or storeroom opening?
Yes. The trim is listed for classroom/storeroom as well as office, privacy and apartment applications. In practice the outside lever stays locked and a key retracts the latch, which is how most classroom and storeroom entries are run.
