This is a problem solving extra short latch for doors with a narrow stile. Fits old fashioned knobs or levers with a square spindle. Clever design fits 8mm spindles on the square and 7mm spindles on the diamond.

See an example used with an Emtek lock. That entire combination is orderable here.

Works with Emtek passage locks using exposed screws on standard rosettes. Requires about a 60 degree rotation to fully retract. The hub will continue to turn to 65 degrees, however at 65 degrees, the latch is over retracted. Standard Emtek passage sets use a 60 degree latch. Emtek locks using concealed screws or with Stretto sideplates require a 28 degree latch. Please note: Emtek locks with the 28 degree upgrade latch will not work with this latch. If you intend to use this latch with an Emtek lock, order the lock with the standard 60 degree latch. Also, you need to replace the die-cast Emtek spindles with a 8mm solid steel spindle.

Dimensions:

  • Mortise size: 5/8" wide x 1-1/4" tall x 2-5/16" deep.
  • Faceplate size: 2-1/4" x 5/8".
  • Backset: 1-3/4".
  • Strike plate: 2-3/4" x 1-1/8".

Also, compare to this 1-3/4" backset magnetic passage latch.

    Was able to adapt this product to accommodate a Schlage interior passage door lever. Works perfectly, well designed and manufactured. Excellent customer service.

    Needed a short backset

    This product is exactly as described. If you need a short backset latch for a special situation, this works perfectly. Had to grind the spindle for a Schlage lock a bit with my Dremmel tool to make the perfect fit, but it was really no problem.

    The company contacted me to tell me that my order would be delivered that day. It came to me in sturdy packaging and fit my needs perfectly. Thank you Kilian for fixing my issue. Will definitely order again.

    I was pleasantly surprised! I knew what I wanted, a narrow backset latch & mortise bolt for a contemporary door I had built. I saw that it was available at Killian Hardware but I had some questions. I called in & spoke to a gentleman in the hardware department who answered all of my questions & recommended some additional parts I would need to make sure that all worked properly. It was like going to a old time local hardware store without even having to leave my shop! Thank you Killian's!
