Precisely set staples into corrugated cardboard boxes. These staplers have adjustable settings that control the tightness of the staple clinch and the depth of the staple, which prevents the staple from coming into contact with the box contents.
The anvil in the stapler clinches staples with 5/8" leg length for single-wall boxes and 3/4" leg length for double-wall boxes. Replacement anvils are sold separately.
