The Air Handler Floor Pump offers the same gauge accuracy and pressure rating as pumps costing 10 to 15 times the price. With a super-smooth polished aluminum barrel, it's a pleasure to look at as well as to use, and will inflate a 700c x 23mm tire to 100 p.s.i. in 20 strokes.

The ultra-stable steel base measures 9 ¼” across, and Kraton rubber grips provide maximum comfort and ergonomics.The easy-to-read two-inch industrial-grade gauge is positioned low to protect it from falls, and has an adjustable red indicator arrow to make it easy to find your favorite pressure.
