Andersen Double-Hung Window Opening Control Device Kit in White Color

This is the right window opening device or child security latch for up down sliding windows for Anderson series. This will allow you to pass inspection if you have windows opening into a pool or if you have a small child or a second floor window you worry a child can open or for general purpose security reason. This looks good and can be easily installed on wood or even vinyl windows. Very happy with the purchase. Use instructions correctly, consult your local code and be aware of fire safety regulations in your house or area (since this would limit escape too so you must use it in accordance with your local safety measures. We are happy with this purchase!

Easy to install. Functional but somewhat expensive.

I have Andersen dual hung windows and I. tried installing these and the glass cracked. The reason I bought these were because I thought they would be compatible with my windows. But sadly not!
