FAQ:

Q: Do you need a keyboard extender for your desk?

A: Oftentimes, your desk just doesn’t have room for all of its contents plus your keyboard. That’s why investing in a desk extender specifically for your keyboard is a great idea. Our experts have compiled this list of the best desk extenders out there for you. .

Q: What to use to secure a corner maker to a desk?

A: If frustrated with the fit and unable to secure the corner maker to your desk, as is the case for me, just wedge folder paper towels or another type of wedge inside the edge of the desk and space between the corner maker. Holds snug and keeps the desk from being damaged.

Q: Can you put a wedge on a high rise desk?

A: I ordered it for a office desk to fill the corner gap. Unfortunately the screws as you can see in the picture that hold the wedge on stick down to far and hit your legs. This would work if you had a high rise desk that you don’t have to worry about hitting your legs. Nice quality, sturdy. Screws don’t actually fit.
