'Cornerbead Clincher w/Mallet, Number of Pieces 2, Size 16 1/4 x 7 x 5 1/2 In, Aluminum/Rubber, Cast Aluminum Crimper, Wood Handled Rubber Mallet, Includes Clincher and Mallet'

From the Manufacturer

The Goldblatt Corner Clincher and Mallet is the perfect way to properly seat drywall corner bead. This tool provides consistent, professional results. One strike with the included rubber-head mallet drives the corner bead flush and tight to the corner while crimping the edge to secure it in place. The cast aluminum body, stainless steel head and precision ground teeth make this a superior tool.
