CINCINNATI, Ohio — SENCO has added two new pneumatic nail guns with increased magazine capacity to its JoistProTM line of metal connector nailers.

The new JoistProTM150MXP and JoistProTM250MXP, used for fastening metal structural connectors like joist hangers, seismic/hurricane straps and rafter ties, feature several design innovations beyond magazine size that improve durability and boost productivity on the job site.

JoistProTM150MXP

The JoistProTM150MXP fires 1.5-inch nails ranging from .131 to .148 inches in diameter. Its new magazine holds two strips of SENCO paper-tape collated nails, cutting downtime for reloading in half. The 150MXP also features a redesigned adjustable hook made from heavier-gauge steel, allowing the nailer to be securely hung from a tool belt or rafter when not in use.

Weighing just 5.3 pounds, the 150MXP is more than a pound lighter than its closest competitor, allowing pros to work longer with less fatigue. The tool features a nose design that exposes each nail tip before it fires for exact placement into the pre-punched holes in metal connecting hardware.

JoistProTM250MXP

SENCO’s more powerful JoistProTM250MXP fires 1.5-inch to 2.5-inch nails ranging from .131 to .162 inches in diameter. Like the 150MXP, the 250MXP features an increased-capacity magazine that holds two strips of paper-tape collated nails. It also includes the updated belt/rafter hook.

Additionally, the 250MXP features an all-new nosepiece that provides accurate nail placement into pre-punched metal framing hardware. The redesigned nosepiece is sharper and more pronounced, making it easier to probe the pre-punched holes on metal connectors and achieve a perfect, flush drive every time. Durability updates have also been made to the 250MXP’s depth-of-drive wheel, which allows users to drive nails to a consistent, controllable depth.

Despite its heavy-duty construction, the 250MXP still weighs nearly 2 pounds less than its closest competitor. The tool features a rear-load magazine that captures the fastener by the head, so there’s no need for manual adjustments when switching between standard 1.5-inch nails and the 2.5-inch nails required by code in hurricane and seismic zones.

Hallmark Features

Both the 150MXP and 250MXP include all the leading features that are hallmarks of the JoistProTM line, including: a 360-degree adjustable exhaust port that directs blowback away from the user; a lockout that prevents dry firing and signals the user when it is time to reload; an overmolded, full-comfort grip that reduces fatigue and minimizes slipping; and industry-leading power to drive nails into even the toughest substrates, such as engineered lumber.

Alongside the new nailers, SENCO unveiled several new configurations of metal connector nails for use in JoistProTM systems. The hardened nails are available in boxes of 3,000 .148-inch by 1.5-inch nails; 2,500 .148-inch by 2.5-inch nails; and 2,000 .162-inch by 2.5-inch nails.

The JoistProTM150MXP and JoistProTM250MXP come with five-year limited warranties.
