Solid brass mortise cylinder
This 1-1/8" cylinder is machined from solid brass bar stock to OEM specifications. The US3 polished brass finish suits both indoor and outdoor doors. A 5-pin tumbler and Schlage C-K keyway provide standard keyed-different security for residential and light commercial entrances.
Threaded installation with standard cam
The cylinder threads into any mortise lock body with a 1.150 x 32 UNS thread and a 1.360 (34.5mm) diameter face. A Standard Cam #1 is fitted; other cams may also work. Verify the existing lock body matches the thread and face dimensions before fitting to avoid cross-threading or loose engagement.
Fits common 1-1/8" mortise prep
The 1-1/8" length covers typical door thicknesses found in standard mortise preparations. It will not suit thicker doors that require a longer cylinder or thinner doors needing a shorter size. The 5-pin tumbler offers conventional key control; high-security or master-keyed systems would need a different cylinder design.

Questions about this item
How can I confirm the 7185SX1-03 cylinder operates correctly after installation?
Insert the supplied key and verify smooth rotation through all five pin positions; the bolt should extend and retract cleanly without binding on the 1.150 x 32 UNS threads.
What components are included with the 7185SX1-03 and what must be purchased separately?
The box contains the solid brass mortise cylinder with Standard Cam #1 and two cut keys for the Schlage C-K keyway; mounting screws and any additional cams are sold separately.
Which cylinder length should I select for my door thickness?
Choose the 1-1/8" length when your mortise pocket measures that depth; other lengths are offered for thicker or thinner doors.
