The Fastcap CROWN MOLD CLIP is a set of Four Crown Molding Installation Clips. FastCap’s new Crown Clips are used by lightly fastening them to the wall using drywall screws with the hook positioned slightly lower than the installed bottom edge of the molding. The crown molding is then laid in the hook and supported while the molding is nailed. The clip is removed before the molding is nailed by simply sliding it to the left about 3/4-Inch and popping it over the screw head. Crown Clips are completely reusable. Hangers are approximately 3-1/2 Inches tall and 1-1/4 Inch wide, with a 9/16-Inch deep hook. Hangers may be located up to 48-Inches apart, but plan on using one hanger for every 36-Inches of length.
