| 1. A system for forming a window opening in a poured concrete wall, the window opening being adapted to retain a window therein,
the poured concrete wall being formed from cured concrete previously poured between spaced wall forms, the system comprising:
a reusable generally rectangular window buck having four sides and being adapted for placement between the spaced wall forms
to divert the poured concrete around the window buck to form the window opening in the concrete wall, the window buck being
removable from the poured concrete wall for subsequent re-use after the wall forms are removed from the poured concrete wall;
and
a plurality of retainers coupled to at least three sides of the window buck while the concrete is being poured around the
window buck, the retainers each being adapted to be at least partially embedded in the concrete wall proximate the window
opening and adapted to be uncoupled from the window buck when the window buck is removed from the poured concrete wall, the
retainers each being adapted to provide an attachment location for securing the window within the window opening.
