Solid brass mortise cylinder

The MAXTECH cylinder is a solid brass mortise lock core with a 1-1/8 inch length and US3 polished brass finish. It uses the Arrow AR1 keyway and ships keyed different for individual access control. The 1.150 x 32 UNS thread and 1.360 diameter face match common mortise housings. Standard Cam #1 is installed for typical latch operation.

Indoor and outdoor durability

Brass construction resists corrosion on exterior doors while the polished finish withstands interior handling. The 5 pin tumbler mechanism operates mechanically without electrical draw or moving fans. No thermal output or acoustic signature is produced during normal locking cycles. Thread tolerance of 32 per inch ensures consistent engagement in the mortise body.

Standard cam and keyway flexibility

Standard Cam #1 fits most common mortise lock bodies without modification. The Arrow AR1 keyway accepts compatible blanks for duplication at standard locksmiths. Keyed different packaging means each cylinder requires its own unique key. Builders needing master-keyed sets or alternative cam profiles must source those separately.

Questions about this item

How do I install the 1.150 x 32 UNS thread cylinder and which step is often missed?

Thread the 1-1/8" brass cylinder into the mortise lock until the 1.360" face sits flush; the step often missed is aligning the Standard Cam #1 with the lock's retractor before tightening the set screw.

What maintenance will the 5-pin Arrow AR1 cylinder need over time?

Lubricate the 5-pin tumbler annually with dry graphite powder; avoid oil-based sprays that attract grit into the Arrow AR1 keyway and cause sticky pins.

What limit appears first on a high-traffic door with the polished brass finish?

The US3 polished brass coating wears through on the cylinder face before the solid brass body or Standard Cam #1 show mechanical fatigue.
