Each Little Green Sucker Hardiplank Installation Tool has a small device called a venturi that produces a powerful vacuum as air passes thru it, allowing the unit to suck itself to the last piece of siding installed. The adjustable spacing rod hooks under the lip of the siding, assuring you even spacing. You then place your next row of siding directly on top of the units, and secure it.

Consuming less then 1 cubic foot of air per minute at 40 psi, two units can easily be operated off one portable air compressor. The air is exhausted out of a port on the face of the unit. To release the Little Green Sucker Hardiplank Installation Tool , simply put your finger over the exhaust port and back pressure will release it into your hand.
