Installing transitions against carpet

I recently had some Bruce engineered hardwood installed (ABC3201 Oak - Gunstock | ABC3201 | Hardwood) in a family room. That room connects to a study with carpeting. I purchased the corresponding Threshold T97131141 to go under the doorway and transition between the hardwood and carpet.

A few questions:

1.) What's the best way to install the carpet next to the threshold? Like this?




I've read that a new carpet tack strip should be placed down about 1/2" away. Do I have to use a tack strip? Can I use carpet tape instead? I was trying to find a way to do this myself without having to use a tack strip and the corresponding tools needed (carpet kicker).

2.) Assuming I have to use a tack strip, do I tuck any of the carpet underneath the threshold, or does the carpet butt up against threshold?

3.) Is it OK to glue the threshold "lip" down to the concrete using Liquid Nails?

I've included some photos below.













Thanks!

 

Kind of looks like the carpet is already cut, if so, it will be hard to stretch it over the tack strip and tuck it down. If not, then the tack strip will keep the carpet from walking and moving. Yes you can glue the transition down, but you need to use an aggressive glue. Regular liquid nails won't do, you need one rated for flooring and the constant pounding it will take. I use a special adhesive for both tack and strips called Chemrex. I think you can order some on line, or go to a specialty carpet supply store (usualy tucked in the corner of a industrial park).

 

What about using a carpet tape (they sell permanent carpet tape at Lowes) in lieu of a tack strip?

 

No experience with tape, I do it by the book - tack and tuck. But you would have to cut the padding back to make room for he tape and the carpet would dip down during the last 3 inches at the transition.
