Abstract
A hose extending and retrieval system and method used for loose-fill insulation operations that includes a hose member that is taken-up or fed-out from a hose storage container with a gear mechanism. A hose extending and retrieval system includes a hose member having a helical rib traversing therethrough, a hose storage container comprising an aperture forming a conduit, and a gear mechanism including a first gear and a second gear disposed on opposing sides of the hose member, wherein protrusions on the first and second gears interlock with the helical hose member. The gear mechanism interlocks with a helical component on the outside of the hose to provide sufficient operational impetus.
