Roofing contractors and siding installers rely on the Metabo HPT N3808APM Cap Stapler for securing synthetic underlayment, roofing felt, house wrap, and insulation with code-compliant holding power. It excels in high-volume fastening on asphalt shingles and tar paper over wood decking, delivering superior shear values through 18-gauge staples paired with 1-inch plastic caps. Unlike the Stinger CH38A Auto Hammer Cap Stapler limited to 3/8-inch lengths for lighter duties, the N3808APM handles 7/8 to 1-1/2-inch staples with 200-piece capacity magazines, tool-less depth adjustment, and lightweight 4.8 lbs design for all-day comfort and efficiency on demanding jobsites.
