#1 Q:   Hi, I need same register for 12 spiral duck, do you have it?
A:   Unfortunately these only go to 10 inch. We have asked for them for more sizes, so I am hopeful in the future we will

#2 Q:   The description says these are adaptable to 6 duct. Does the paperwork supplied with the registers provide instructions on how to adapt?
A:   They pop right in on 8 and 6...the 10 needs to have the sides filled a bit with sealant but it goes on pretty easily...I do not believe instructions are included.

#3 Q:   I have 8 round pipe. What size hole is needed to accommodate these? No backside pictures or side angle pictures so hard to tell. Do these just cover pipe or do these have rectangular insert molded in? Thanks
A:   These just cover the rectangular hole/opening in the duct. You cut the opening to the recommended size for the grille.

#4 Q:   4 X 12 spiral duct grille for 8 diameter duct. Adaptable to 6 and 10 ductsWhat does adaptable to 6 ducts mean? I have 6 ducts.
A:   8 inch is a perfect fit, mostly the same with 6 inch with some caulk required. The 10 does need to have the sides built up with caulking or foam strips to fix the gap and make the grilles seal.

#5 Q:   Can your spiral duct registers be used on regular round metal ducts? I want to add a few vents to my round duct return
A:   Sure, as long as the ducts are 8 inch diameter.

#6 Q:   Can I cut a hole in the duct and attach this to heat an area of my basement? Or, is this a cover that attaches to something else that attaches to the duct?
A:   These attach directly to the duct assuming its the correct diameter for the grille.

       Asked on 2022-02-09 by Jen
#7 Q:   Can the register be closed when air not needed?
A:   The fins are fixed and there is no damper so they cannot be closed off.
