PRODUCT DETAILS

DESCRIPTION

Power through framing jobs without the hassle of hoses and compressors with the FLEX 24V Brushless 21° Framing Nailer. This cordless framing nailer delivers high-speed power by driving up to 3 nails per second with zero ramp up time. It drives up to 1,100 nails on a single charge with a 5.0Ah lithium-ion battery for extended runtime. The nail gun features a depth adjustment dial to easily set the ideal depth when driving fasteners, and its dual LED worklight delivers better visibility in dark work areas. The cordless nail gun toggles between bump and sequential firing modes and has a nail indicator to easily see how many nails remain in the magazine. Dry-fire lockout avoids blank firing and damage to your work when the nail supply is exhausted. Its heavy-duty belt clip can be mounted on either side of the tool and features a lead-in profile. A convenient pivoting rafter hook allows additional easy storage when not in use. The framing nailer accepts 2-inch to 3-1/2-inch fasteners. This cordless nailer delivers the FLEX Advantage of unmatched battery power, runtime, and fast charging. Kit includes the 21° Framing Nailer, 5.0Ah lithium battery, 160W Fast Charger, rafter hook, belt clip, (3) no-mar tips, and a FLEX bag.
