    Best way to secure duct test flange to a ceiling grille?

    I have the older version of the Retrotec DU200 duct test kit, and it doesn't have the spring loaded hooks to easily connect the flex duct flange to a ceiling R/A grille.
    So, I'm sure some of you have found ways to make this easy without having to tape them in place.
    My thoughts are to:
    1. Drill holes for hooks and make my own spring loaded fasteners.
    2. Stick magnets around the perimeter of the flange to make the connection even easier. (won't work on aluminum)


    Any input would be helpful?

    Maybe rare earth magnets installed inside the duct/register you want to hook to and then magnets on the outside of flow hood that hold it up?

    I dont know what you're working with, Ive never seen one before. So this idea may be total garbage.

    On page 2 of this guide for the DU200 they show a pic of taping the flange to the grille.

    I don't have the new model US341 that has hooks

    I’ll invest in vent caps once the equipment starts paying for itself. Otherwise, I can fabricate a shallow pan out of sheet metal with a foam edge if I want to go that far. I’m thinking a couple hooks would work pretty well with the existing flange.
