The Vanguard ALTA LAA Low Angle Adaptor is a 4.5" aluminum center column that is compatible with Alta Pro 2 and Alta Pro 2+ tripods. Because of the shorter length of the column, it allows your tripod to splay the legs further out and bring the tripod down to a lower shooting angle. Furthermore, the column is faceted, which prevents it from turning or spinning while sitting in the yoke of the tripod.
Compatibility
Alta Pro 2 and Alta Pro 2+
