## Questions & Answers

**Q: When well the product exist ?**
A: I'm responding here about 45 minutes after first seeing the question - because I started laughing uncontrollably from Kelly's answer, and it took that long to compose myself enough to type.

**Q: Does the contour lock in place when set?**
A: Yes it stays locked.  As a matter of fact, the tines are so firm that it's actually pretty hard to move them out of place.

**Q: What is the actual width able to measure or contour with this gauge? I see product description and tech details don't match up.  ANYONE have exact?**
A: Looks like somehow the metal and plastic models have been mixed up.  The metal one can reproduce a contour six inches long and two inches deep.

**Q: When will the 10 inches gauge will be available?**
A: This messaging Q & A is about the usage or how it might be used for other applications.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great tool
*by A***. on 16 September 2025*

Used it a few times it has come in handy

### ⭐⭐⭐⭐⭐ Excellent bit of kit
*by M***M on 20 October 2016*

Nice USA made product. Smooth action on the pins makes it easy to obtain an accurate profile and there is sufficient friction to hold them in place to transfer the outline to your chosen surface. The only minor issue was that the packaging was poor but it did arrive very quickly and was undamaged.

### ⭐⭐⭐⭐ Good but a couple of issues to note.
*by P***X on 19 May 2022*

It definitely saves time and mistakes as the hole is always 5mm from the edge. Also, as it is clamped down, there is no chance of it moving during drilling - so great. But 2 demerits: 1) The guide holes did not line up with the (Blum) hinges I was using. I don't know which manufacturer's hinges the guide holes are designed for. 2) The design does not allow for certain 35mm drill bits to be used. I bought an expensive Bosch drill bit and the shaft changes diameter right at the point where the locking screw (to set the depth) locks in. So, if you want to use an alternative drill bit to the one provided (which does the job okay but will blunt), you will have to hunt around for one with a longer thick shaft section.
