Prime-Line E 2330 Mortise Keyed Lock Set with Satin Nickel Knob – Perfect for Replacing Broken Antique Lock Sets and More, Fits 1-3/8 In.-1-3/4 In. Interior Doors, Satin Nickel (Single Pack)

This door knob with lock matched exactly the one I had which was at least 60 years old, so there wasn't much to do except take the old one out and install this one. The only problem I had was that the mechanism was a bit stiff, but after a little lubrication it now works perfectly. Very happy with my purchase and also with the supplier's fast despatch; thankyou.

Es de buen material y buena calidad y funciona muy bien y buen precio y fácil de instalar,me gustó mucho.

Debido a que la casa es antigua, no hay muchos establecimientos donde se encuentren este tipo de cerraduras, quedo instalada muy bien, solo un par de orificios a la puerta y contrapuerta para su instalacion, pero quedaron ocultos. Muy buena ccompra, y se ve elegante, old fashion. Voy a comprar el resto de las cerraduras para las puertas remanentes de la casa

This Mortise Lock updated our antiquated rear-door that had an incredibly old, and barely functional doorknob that didn't latch or lock. Setup was very easy, even though it required me to chisel away at the door a bit (as anticipated, I knew the size wouldn't match up exactly), so encourage anyone buying to measure first if they don't want to work on the door/ jamb at all. It looks sleek and works exactly as expected!

When utilising the instructions to reverse the handing of the door it doesn't work. After multiple tries to understand the limited information given I have discovered that reversing the handing results in a lock mechanism so poorly aligned internally as to render it non-functional
