What this lock is and who it fits

The Kaba Group 7205YA1-03 is a solid brass mortise cylinder with a Yale YA1 keyway and a US3 polished brass finish. It measures 1-1/4" in length and uses a Standard Cam #1. The cylinder face is 1.360 inches in diameter. It is designed for indoor and outdoor use on doors that accept a 1.150 x 32 UNS thread size.

Check your door before ordering

Verify that your existing mortise lock body accepts a cylinder with a 1.150 x 32 UNS thread and a 1.360 inch face diameter. Confirm the door thickness matches the 1-1/4" cylinder length. Ensure the lock mechanism works with a Standard Cam #1. This cylinder is keyed different and uses a 5 pin tumbler with the Yale YA1 keyway.

Durability and daily operation

The solid brass construction resists corrosion in indoor and outdoor environments. The 5 pin tumbler mechanism provides standard security for residential or commercial doors. The polished brass finish maintains its appearance with routine cleaning. No electronic components or batteries are involved, so operation remains mechanical and consistent over time.

Questions about this item

What is included in the box and do I need to purchase anything else to install it?

The box contains the solid brass mortise cylinder with Yale YA1 keyway, finished in polished brass US3. It comes keyed different with two keys. No additional parts are required if your mortise lock accepts a 1.150 x 32 UNS thread and 1.360 diameter face.

Which size should I choose for my door thickness?

This cylinder is 1-1/4 inches long. Measure your existing cylinder or the mortise pocket depth to confirm this length matches; other lengths are available for thicker or thinner doors.

What does the 1.150 x 32 UNS thread specification mean when fitting the lock?

It defines the cylinder's threading so it screws into a mortise lock body with the same 1.150 inch diameter and 32 threads per inch UNS standard, ensuring a secure fit without adapters.
