It’s always guesswork, when applying a shade to a door, whether HOLD DOWNS are appropriate or no. The giveaway is when a hold down is viewed:
As you can see, the hold down itself is screwed (from the back) ONTO the door; the slight protrusion at the front of the hold down fits into a hole in the end cap. Since everything fits together, and needs to screw in, there is no maneuver-room if the shade is installed as an “inside” mount.
Will the bottom flap if used on a door when NO hold down is used? Definitely.
A standard, therefore, is to do an “outside” mount — and use hold downs!
