Please select from the options at the bottom of this page to customize your Genexhaust extension kit that will fit a Yamaha EF2400iSHC or EF2000iS model generator. Prices vary depending on which type of hose you choose and the length of hose you select. Prices are shown as you make your selections. Scroll through the images to see the available hardware for this model. All available extra options will be shown as you make your selections. Images shown are with quick disconnect, but that is an additional option. You have the option of adding a discounted quick disconnect and discounted through-wall kit to your order. Quick Disconnects are only available for 1.5″ diameter hoses. Through-wall kits are available for 1” and 1.5” diameter hoses. A Through-Wall Kit mounts in the wall of your building or enclosure and allows you to hook up your extension hose and vent your generator exhaust outside. Kits are available in longer and shorter versions for 1" and 1.5” hoses (both for steel or silicone hoses). The longer kit is more suitable for going through thick exterior walls, whereas the shorter kit is more suitable for going through a single layer wall, such as a plastic utility shed. The longer version of the Through-Wall kit is available in Single or Double Shield. A "Single Shield" kit is one layer of metal, and a "Double Shield" kit has two layers of metal with a space in between each layer, and offers better insulation from the heat of the exhaust. The shorter version of the Through-Wall kit is available in Double Shield only. Please make a selection in EACH dropdown box to ensure order accuracy. Please carefully review your selections before hitting the "Add to Cart" button, as changes cannot be made to your package in the cart.
