Abstract: Certain example embodiments of this invention relate to internal grid keepers for insulating glass units, and/or insulating glass units incorporating the same. The grid keepers of certain example embodiments may include a shoulder bent into an acute angle and may include one or more stamped features on or proximate to the shoulder for engaging with a punched, hollowed, or otherwise formed feature in an edge seal, along with one or more stamped features on an elongate portion extending from the shoulder for engaging with a grid or muntin. In certain example embodiments, the keeper may be on level with or slightly lower than a primary seal so as to reduce the likelihood of the keeper interfering with the seal.
