Liberty Mountain's ABC Huevos are among the best wired units available. They tumble the heads longer than most, making them easier to place and handle. Constructed of the finest 6061-T6 aircraft aluminum available. The steel cable is galvanized and then swedged with copper sleeves, increasing the unit's overall strength and durability. Each Huevo is then tested to half its rated strength to ensure quality and performance.
