FAQ
Most professionals hang their backpack blowers when not in use. You can easily buy a backpack blower rack online or install some hooks yourself. The hooks simply support the blower’s weight from the carry handle. Units available to buy online often feature a fold down steel arm that locks the blower securely in place.
