Review: Great find - This brand of gate and this extension has been a lifesaver for us. Two dogs that have run out into the yard and one got a skunk . This allows us to get a view of the yard before we let them into the yard. The gate is high quality, sturdy, good looking gate. We have another one that is still going strong after seven years of Constant use.
Review: Very well designed Pet Gate Extension - We built our deck with a 4' wide set of stairs...anything less and it's very hard to carry up large grills, tables, etc... But, finding a pet gate that would work on such a wide stair opening was difficult. We found this Cardinal Pet Gate with the optional Extension a perfect choice. This gate system is very strong, coated to prevent rust from the elements, and the hinge system was easy to install. Plus the fact that this optional extension was available allowed us to have our staircase closed off. The Cardinal system has an adjustable main gate, which allows coverage over a nice range of openings. Our 4' opening was just a bit too big, thus we also purchased the extension, which bolts to the main gate making a nice solid gate. Make sure to purchase the stainless-steel screws so you can have rust free protection. One note, the locking mechanism seemed a bit weird when I first saw it, but once installed, it is great! We also use this as a baby gate and the locking mechanism can only be opened by pushing two outer taps at the same time that you lift the gate slightly...very difficult for a toddler...impossible for our cats!

### ⭐⭐⭐⭐ If only...
*by L***P on August 10, 2021*

Great add on to make Cardinal's excellent safety gates (both the indoor & outdoor versions) fit openings over 42.5". Looks great, super easy to add to the installation with just a couple bolts & washers. That's where it gets quirky The gates themselves, all 3 color choices, come w/stainless steel hardware (outdoor gates), but the indoor gate hardware is not ss. The extenders have ss hardware for only the brown version. You can either use a brown extender with black or white gates, buy a ss hardware pack (3 bolts + 3 washers) to replace what comes packaged, or go buy those pieces at a local hardware store for $2 or so. Seems like an avoidable customer inconvenience w/ an easy customer centric solution that would be pennies to just upgrade these pieces in all extensions.
