The Primatech 250ASG is a professional-grade pneumatic flooring stapler designed for hardwood floor installation. Built with a 15.5-gauge capacity and a 1/2" crown, this powerhouse tool features the innovative PrimSurfer bearing-assembled roller base with two-way side shift for smooth, precise movement across your work surface. The high-capacity S-Lbo staple channel magazine holds up to 230 staples (5 strips of 46), reducing downtime and keeping your workflow moving. Weighing 12 lbs and measuring 15" in length, the 250ASG is engineered for durability, with a Primpact striking module featuring wear rings rated for over 1,250,000 cycles. The rotating ergonomic extension handle allows for adjustable positioning, while the smooth dual-action recoilless striking mechanism ensures perfect stability with dimple effect reduction. Self-regulating penetration power independent from mallet blow guarantees consistent results, and the finely threaded screw-in cartridge assembly makes maintenance minimal on the job site.
