Salco offers both OEM Bostitch SW7437/ SW9040 and our own interchange WSW7437/ WSW9040 staples (Interchange staples are published on this page). If the carton-closing tools you are using are in good condition, either staple will work perfectly. In circumstances where customers have difficulties with our staples, or OEM Bostitch, it is invariably found to be caused by worn anvils and drive-blades in their staplers. This occurs occasionally with constant heavy use, more commonly from the use of inferior quality staples that jam in the tool and cause damage to the noted parts. Both the Bostitch and our Salco SW7437/ SW9040 staples are unconditionally guaranteed to run perfectly in tools in good condition.
The WSW is our Salco brand made in Germany. Bostitch brand are available at extra cost. As Bostitch brand staples are not listed at our web store, if you wish to purchase them please contact our customer service Toll-Free at 1-877-463-2531.
