The weight of your tools is very important when you’re working 12 hours a day. Holding a heavy hand-tool all day long can increase fatigue, stress, and pain on the forearm, wrist, neck and ultimately on the entire body.

Rubber Pads on the Body: It doesn’t slide off the roof

The tool has rubber pads on the sides to keep it in place even on the steepest roofs. When you’re not using it, you can securely put it down on the roof without the fear that’ll slide off.

These small rubberized pads create friction with the pitched roof and keep your tool in place.

Power Source: Pneumatic (Air-Powered)
