Terrible product. Doesn't fit on standard (Nutone) central vacuum outlets. In fact, I nearly destroyed an outlet cover trying to get this thing back off after first trying to get it all the way on! Was hoping this solved my retrofitting problem in an older house with thick plaster walls, but it didn't work. I should have listened to the previous negative reviews. Fortunately, it didn't cost that much.

(MD Notes: Unfortunately, we did have a batch of extensions that were smaller in diameter. We have since resolved this issue and reached out to the customer with a couple of options.)

The extensions I received did not fit properly because the female end is slightly too small. It appears to be a matter of quality control. After enlarging the end everything else went together perfectly. Notified MD, response to issue was less than responsive.

(MD Note: We confirmed that we received a faulty batch of extensions. We reached out to the customer with a few options to help remedy the issue.)

Purchased a replacement outlet because the original did not connect to pipe. This part was useless, did not fit new outlet or pipe in wall. You folks need to ID an extention that would at leased fit the outlet you sell.

Currently waiting on another part ordered from you that hopefully will fit.

I got this to extend the reach of the metal inlet valve in order to install the valve through a hardwood floor and subflooring. The fit of the extension on the inlet valve is so tight that the extension will only push onto the valve a little over a quarter inch rather than the full depth of the extension, which results in the collar of the extension hitting the mounting bracket. Both of the extensions purchased had the same problem with both of the valves. There's no problem with the diameter of the valves themselves; they fit the mounting brackets perfectly other than for the length. (MD NOTES: On metal inlets they can be tight. If they only go on a bit it may or may not be an issue. If it is, try cutting the wider side to a shorter distance, or the narrower side depending on what is hitting where.)
