W3 Dovetail Keys - approx. 1/2" x 3/8"
Hoffmann Dovetail Keys, size W-3, are a popular size for a wide range of woodworking applications including miter joints, butt joints, compound miter joints and end-to-end joints.
The W-3 Dovetail Keys are larger in both width and height compared to W-2 Keys, and are therefore exerting more clamping pressure and holding strength in all types of miter and butt joints.
Typical uses include cabinet and furniture frames, straight and curved handrail joints, heavy column bases, bar and chair rails, wooden ceiling systems, outdoor furniture as well as institutional and commercial mitered cabinet doors. In addition, heavy wood components with large cross section, such as casket lids and casket side panels, sauna and steam-room components, post and beam construction etc. often require the use of W-3 Keys.
Special applications, for example mitered doors with heavy glass or mirror panels and floor-to-ceiling type doors for laboratories and schools, are often joined with W-3 Dovetail Keys as well.
