Cabinet elbow catches are for double cabinet doors where one door opens first, second door is opened as needed. Use elbow catch to secure second door. Mounts inside cabinet, behind second door. When installed: open first door, reach inside release elbow catch, allowing second door to opened.
These inexpensive elbow catches provide a vintage appearance. They are stamped steel. Thumb release easily engages catch. Use #3 screws.
I couldn’t find a mortised lock to fit a door on an 19th century English cabinet, until I found Paxton. I’m a professional refinisher & have many suppliers that I use. Paxton is now my go-to, number 1 seed.
