About this item

  • Compatible with Mid-Century Doors: If you have a mid-century door with a 5" backset, replacing it can be costly. Our latch allows you to preserve your vintage door while updating it with modern handlesets, saving you thousands of dollars.
  • Unique 7.7mm Square Interface: Unlike the half-moon openings found on other latches, our 5" backset entry latch features a 3.03" square opening, ensuring it fits the square interface of most knobsets and 90° leversets on the market.
  • Installation Requirements: This latch requires a 2-1/8" diameter cross bore hole on the door face and a 1" diameter edge bore hole. Depending on your door and handleset, you might need to make some adjustments to fit it perfectly.
  • Retro 5-Inch Backset Solution: In the 1950s and 1960s, 5" backset door hardware was the norm. Nowadays, it's hard to find. If you're on the lookout for this specific backset size, our product is the perfect solution to meet your needs.
  • Important Compatibility Note: Our latch is designed to match standard satin nickel finishes and works best with 90° rotatable lever handles. Ensure your lever handle is 90° rotatable to guarantee the latch tab fully retracts, unlike the common 45° levers which may not function correctly.

The 5 inch mechanism fit and worked perfectly. The door handle works well but it is a bit jggly and seems a little cheap. Does th job though.

We had a door where the knob needed replacement. The door had a 5" span. We were told by more than one person that a replacement knob did not exist. Tried Amazon and viola. Really good quality. Wish it came in gold to match the old hardware. Will buy again.
