A cast-in anchor system for anchoring objects to concrete structures. The preferred system uses an extruded cast-in anchor and an extruded bolt retainer. The cast-in anchor is embedded within concrete with a face left exposed. The bolt retainer has a bolt inserted through it and is placed within an anchor channel on the exposed face of the cast-in anchor.
