It runs 2-inch to 3-1/2-inch angled strip nails on paper tape collation, with an 80-nail magazine capacity that keeps you working longer between reloads.Rear loading keeps the nose profile compact for working in corners and tight bays, while the pneumatic drive runs on a 70 to 120 PSI range, giving you room to dial in power for different lumber and fastener lengths. At 11.54 pounds, its built to handle a full day of framing without feeling like a liability by the afternoon. Backed by a 5-year warranty and made in the USA, this is a tool meant to earn its keep on job sites, not just showroom shelves.Loading type: RearMagazine capacity: 80 fastenersFastener size range: 2 inch to 3-1/2 inchCollation: Paper tape, angled stripOperating pressure: 70-120 PSIWarranty: 5 years, made in USA
