These were just what we needed to go with the new inlet valves we ordered. Our outlets are in the baseboards so these were necessary.
this was helpful for me in installing a floor inlet for a Beam vacuum. The floor inlet was installed over a new wood floor and the total floor thickness between the finished floor top surface and the bottom surface of the subfloor added up to one and a half inches. This extension goes between the floor inlet and the metal mounting plate under the floor.
I am adding wainscoting paneling to my home this extension really helped.
Added some decorative paneling just in front of our valve outlets and needed a few extra inches to maintain the proper seal.... glad I found these on-line!
Just what we needed at a very good price
I didn't need these after all, but they would have done what they are supposed to do, if needed.
works like a charm
