It is compatible with 50 series fine wire staples with a 1/2" crown and supports staple lengths from 1/4" to 5/8". A large magazine holds up to 110 staples to reduce reloading interruptions during use. The lightweight aluminum alloy body, ergonomic rubber grip, and sequential firing mode help improve control, comfort, and safety. This air-powered stapler operates at 70-100 PSI and uses a 1/4" NPT air inlet.
