Lets Face It. Drive anchors used on Duck Blinds live in the mud! Or worse, in a saltwater marsh environment. Xceltek offers only 100% Galvanized drive anchors for securing your blind from wind or being floated away. Our XT Series Blinds are designed with holes in the feet specifically to accept a drive anchor. We recommend using at least 4 drive anchors on 8' Lg. and 12' Lg. blinds, and at least 6 drive anchors on 16' Lg. Blinds. Kits can be purchased in Quantities of 4 or 6.
