Hager 3901 SC 26D – Frequently Asked Questions

1) Can I key the Hager 3901 into my existing Schlage C master key system?
Yes, if you order the Schlage C keyway version. It is a conventional cylinder drilled 6-pin and keyed 5-pin, so a locksmith can key it into an existing Schlage C system. If your building runs small format interchangeable cores instead, take the SFIC housing (6-pin or 7-pin) less core and install a core already cut to your system.
2) What is the difference between the 6-pin and 7-pin SFIC housing on the Hager 3901?
It is about which core depth your key system uses. A 6-pin housing takes a 6-pin small format interchangeable core; a 7-pin housing takes a 7-pin core. Order the one that matches the cores already in your facility, because the two are not interchangeable in the same housing.
3) Is a rim cylinder the right type for my door, or do I need a mortise cylinder?
A rim cylinder like the Hager 3901 mounts through the door and drives a rim exit device or a rim night latch with a tailpiece on the back. A mortise cylinder threads into a mortise lock body and drives it with a cam instead. If the lock on your door is a mortise case, the 3901 is the wrong part. The 3901 is the one you want behind a rim panic device or surface-mounted rim latch.
4) I'm re-keying a whole building of doors. Can I get these keyed alike?
Yes. Keying is a required choice at order: keyed alike, so one key runs every cylinder you buy on the order, or keyed different, so each cylinder has its own key. For a fleet of tenant doors that need individual keys, take keyed different; for a bank of doors one maintenance key should open, take keyed alike.
5) Will the Hager 3901 tailpiece reach through a thick door with a rim device?
It ships with the long tailpiece as standard, which is what covers the range of door thicknesses and rim device back plates you run into on commercial openings. Shorter tailpieces on rim cylinders are the usual cause of a cylinder that turns but will not retract the latch.
6) What hardware is included with the Hager 3901, and do I need anything else to install it?
Each cylinder is furnished with a trim ring, mounting plate, and break off screws, plus two operating keys on the keyed versions. That is everything needed to mount it in a prepped rim cylinder hole. The less-core SFIC versions arrive without keys or a core, so plan on supplying the core.
7) What finish does the Hager 3901 rim cylinder come in, and will it match my other door hardware?
626 Satin Chrome is the finish offered, across every keyway and housing option. That is the standard commercial cylinder finish and it reads as a match against 626 satin chrome exit devices, locksets, and 630 stainless trim in most buildings.
8) Is the Hager 3901 suitable for high-traffic commercial doors, or is it a residential cylinder?
It is a commercial-rated cylinder, and Hager positions it for office buildings, schools, healthcare, retail, warehouse, multi-tenant residential, and government facilities. It sits in the 4700 series line.
9) Is there a template for the rim cylinder hole prep on the Hager 3901?
Yes. Hager publishes a product template for this cylinder, T-ED008773, which gives the hole locations for marking the door before drilling. Use it rather than tracing the existing cylinder if you are cutting a fresh opening.
