Hardware

Would Not Recommend

Does the product work? Yes. But you're telling me you can't include screws to mount it? What a joke. For what it costs, you can add two screws. Companies are getting greedy because I've have bought these before and they used to have screws included.

Screw hole identification

A little difficult to figure out how to take the cover off to insert screws but a good look at the end.

Take your old diffuser to the store

The size, 12" X 6" matched up with the size of my old diffuser but the holes were not in the identical locations so I had to return it.

Perfect fit for our 50's ranch

Would Recommend

Refreshing our new home and the original baseboard registers were awful. Decades of paint over rusty metal. Who know how many layers were lead based paint? Much easier and cost effective to replace with new ones. These are a perfect dropping right in to the original spaces. Good quality and factory color matches our trim. I would recommend these to a friend.
