Review: Elegant fixing and just the right size - The size is perfect for visual effect on a solid oak door. They not only do the job exactly as required they look elegant and quality. A good buy; so good I have bought another.
Review: Very poor quality - These are extremely poor quality bolts. they are nowhere near 90 degrees, the main face surface is not flat and the latch lever is not straight and wobbles about. Rubbish, avoid.

## Questions & Answers

**Q: Does it come with a matching loor plate?**
A: Do. not know what you mean by loor plate.
It comes with a plate that goes on the door frame.

**Q: How far does the bolt come out?**
A: 17mm

**Q: what is the cut out depth**
A: Sorry I can't answer that without removing the bolt from my door, but what I can tell you is that I ordered the 150mm bolt and the top section that the bolt extrudes from is 35mm in length.
The seller should be able to provide an exact measurement.
