On October 7, 2009: This product is exactly what I were looking for. I ordered two extensions along with with the extra wide fence/gate which corresponds to this product.They were very easy to install. It is well worth the $$ spent. It is excellent quality and looks good in newer home, almost as if it belongs there. I was having a lot of problems with my two little 6 pound chihuahuas (they cannot get through the bars), urinating around the house while I was gone and this product rectified the problem. They are now confined to an area where it was almost impossible to find a gate/fence wide enough while allowing them to use the doggy door. THIS IS THE PRODUCT! I did a lot of research for the one to meet our needs and this is it. I also spoke to customer service several times for advice and assistance in placing this order. They were terrific!
