Hager 3902 112 SSC US26D KD – Frequently Asked Questions

1) Will the Hager 3902 mortise cylinder thread into my exit device trim?
The 3902 is cut with the standard 1.150 inch x 32 UNS mortise cylinder thread and a 1.360 inch face diameter, so it screws into any mortise cylinder prep cut to that thread, which is what mortise exit devices and mortise trim use. What still has to match is the cam. Hager publishes a cam cross reference sheet for matching the cylinder cam to the device it is driving.
2) Which length of the Hager 3902 cylinder do I need for my door?
Length is picked off the device and door thickness, not guessed. Conventional keyed cylinders come 1-1/8, 1-1/4 and 1-5/8 inch; small format core housings come 1-1/4, 1-3/8 and 1-5/8 inch; the large format core prep is 1-1/2 inch. Order the length your device manufacturer calls out for your door thickness. Too short and the cam will not reach the retractor, too long and the face stands proud of the trim.
3) Does the Hager 3902 SFIC version come with a core and keys?
No. The 6 pin and 7 pin small format core versions are housings prepped to accept an SFIC core, supplied without core and without keys. You pin and supply your own core, which is what most facilities running an in-house SFIC system want. If you need a cylinder that arrives keyed and ready to hang, order the conventional version in a Schlage C or Hager H1 keyway instead.
4) Can I get the Hager 3902 cylinder keyed to my existing Schlage C building keys?
Yes, in the conventional configuration. The Schlage C keyway version can be ordered keyed alike across a group of doors or keyed different, so it drops into an existing Schlage C system. Conventional 3902 cylinders are drilled 6-pin and keyed 5-pin; the Hager H1 keyway option is 7-pin standard.
5) 6 pin or 7 pin small format core prep, which do I order?
Match the housing to the cores your facility already stocks. A 7 pin SFIC housing accepts the full 7-pin core stack used in most A2/A4 small format systems; the 6 pin prep is for 6-pin cores. Both are offered on the 3902 in every length from 1-1/4 to 1-5/8 inch. If you are adding a door to an existing core inventory, pull one of your spare cores and count the chambers before ordering.
6) Can I standardize one cylinder across all the exit devices in my building with the 3902?
That is the usual reason to spec it. Because the 3902 is offered in one finish with four keying paths (Schlage C, Hager H1, 6 pin SFIC prep, 7 pin SFIC prep) and lengths from 1-1/8 through 1-5/8 inch, a property manager can keep one cylinder family across every mortise exit device and vary only the length per device. Order Schlage C keyed alike if the goal is one key for the whole group.
7) What finish is the Hager 3902 mortise cylinder available in?
Satin chrome, 626, is the finish carried across every keyway and length combination of the 3902. That is the standard commercial match for most exit device and mortise trim in satin chrome or brushed stainless, so it coordinates with 630 stainless trim on the same opening.
8) Is the Hager 3902 cylinder solid brass or plated pot metal?
Machined from solid bar brass. That matters on exit device trim in schools, healthcare and high-traffic retail, where a cast housing can distort around the cam and bind. The 3902 is a commercial-rated part, not a residential cylinder.
