We covered clips to help you hang crown molding already, but these crown molding hangers look like a better tool — they’re more substantial and adjustable. The downside of these additional features: You’ll pay $10 for just one hanger, and you’re probably going to need at least two of them.
The hanger is made from ABS. The bracket is angled for handling crown molding with a spring angle of 45°, but you can also use it for moldings with 38° or 52° spring angles. You’ll need at least two hangers to support a 12′ piece of crown molding, and you may need more if the molding isn’t very stiff.
To use the hanger, hammer in a nail behind the crown molding where it won’t interfere or be seen afterward. Hang the hanger from the nail and place the crown molding on the hanger bracket. Adjust the bracket until the molding is in position and lock it by tightening the knob. Once you’ve secured the molding, loosen the the knob, then lift and move the hanger to the right. It’ll slide out from behind the molding so you can use it again.
