Multiple Functions: Weighing only 9 1/2 oz, the stapler is lightweight and easy to operate. Suitable for home, office, and worksite. Works well for upholstery, weather stripping, insulation and more.

Easy to Operate: This stapler is equipped with a quick-release loading magazine on the bottom for fast and easy staple installation and a patented mechanism to prevent jamming. A reload window allows you to see when the supply of the staple is getting low and need to reload.

Ergonomic Handle: Designed with an ergonomic hand slot to minimize the pain your hands face when you spend time stapling. Comfort grip with a non-slip pattern minimizes hand fatigue and ensures a secure grip when fastening for more extended periods—easy-to-squeeze application.
