## Questions & Answers

**Q: Hi, will they arm extenders work with an L-shaped  desk?**
A: I believe it would work for any shape desk.  What matters is if there enough of a ledge underneath desk top to hold the full clamp .

**Q: Where is this made in?**
A: No clue but like everything else probably China

**Q: I don't have quite 2 inches of overhang, its more like 1.75 or 1.875.  will this still work or is it 2 inches minimum?**
A: My overhang is about 1 5/8 … I glued an extra piece of hard plastic to the upper clamps for added surface area contact pressure and desk top protection.  Screwed clamps down TIGHT … works great!

**Q: Where is this made in?**
A: The company is in Great Britain per the business info but do not see where it is actually made (do not see anything on the product itself). But it is very well made (not flimsy or cheap feeling).
