There are two basic methods for attaching an Air Jet Shovel to a Leaf Blower.
In a First Method, a single or double sided foam tape is stuck to and wrapped around a Leaf Blower outlet tube. Then the Leaf Blower outlet tube is firmly pressed into the Tapered Inlet Tube of the Air Jet Shovel.
A Second Method works well when high powered Leaf Blowers such as Backpack Blowers are being attached to the Air Jet Shovel. This Second Method uses Hook and Loop Tape (VELCRO). Several sections of Hook Tape (Rough Side tape) are stuck to the inside surface of the Tapered Inlet Tube of the Air Jet Shovel. These Hook Tape sections are stuck in a longitudinal direction. Typically, four sections of Hook Tape works well. Then a section of Loop Tape (Fuzzy Side tape) is stuck to and wrapped around the outlet tube of the Leaf Blower. Then the Leaf Blower outlet tube is firmly pressed into the Tapered Inlet Tube of the Air Jet Shovel. The Hook and Loop tape adhere to each other and create a strong attachment between the Leaf Blower and the Air Jet Shovel.
