Solid brass mortise cylinder

This solid brass mortise cylinder replaces existing hardware in residential or commercial doors. It uses a Schlage SC1 keyway and is supplied keyed different so each unit operates independently. The polished brass US3 finish resists corrosion for indoor and outdoor installations.

Standard cam and thread dimensions

A Standard Cam #1 and a 1.150 x 32 UNS thread allow the cylinder to fit most mortise locks on the market. The 1.360 inch (34.5 mm) face diameter matches common mortise prep dimensions. Solid brass construction provides durability without relying on plated coatings.

Five pin tumbler limits

The 5 pin tumbler mechanism works only with SC1 profile keys and cannot accept other keyway types. Buyers who need a master-keyed system or a different keyway must choose another cylinder. The 1-1/4 inch length suits doors of a specific thickness and will not suit thicker or thinner doors without a different size.

Questions about this item

What thread standard does the 7205SC1-03 cylinder use, and what does it cap in practice?

The cylinder uses a 1.150 x 32 UNS thread, which caps compatibility to mortise locks cut for that exact thread pitch and diameter.

What physical dimensions must the door prep match for this 1-1/4" mortise cylinder?

The door must accept a 1.360 inch (34.5 mm) cylinder face diameter and a 1-1/4 inch cylinder length with a Standard Cam #1.

How is the 7205SC1-03 installed, and which step is commonly missed?

Thread the cylinder into the mortise body until the Standard Cam #1 aligns with the lock mechanism, then secure the set screw; the step often missed is verifying cam rotation before tightening.
