Pneumatic (air driven) Omer Carton Closing Stapler for the often called for Bostitch SW7437 staple type (1-3/8" wide). Pneumatic ease adds consistency to the exact "clinching" demands expected by various packaging/shipping demands. This model is internationally sourced by Omer, and serves as yet another example of carton closers which are carefully made to match the tough standards required in bearing the Omer name, while each tool leaves our Ita...lian factory only after having been tested. Accepts staple leg lengths up to 3/4" long. Omer's continuing commitment to the industry's carton closing needs, is seen by the industrial performance provided by our 34.18 model.
