#2 Q:   Are these only for use with Airtec ducting? I am trying to replace existing grilles/diffusers. These are the closest in size and look to the old ones that I have found. Thanks!
A:   These are for generic ducting. If you are looking at the model with the damper then make sure it matches the opening/hole size.

#3 Q:   are these for 6 and 8 inch duct size?
A:   The GRD is for 8 inch duct, the GR360 is also for 8 inch and the GR360S is for 6 inch duct. As they do go up in the duct, one would order the size for the duct in place.
