Abstract: An improved glass railing anchor system for multiple glass panels in high-rise buildings which can experience hurricane strength winds, and which includes an elongated base member having two hollow wall sections which create a channel for receiving the glass panels. Aligned with and beneath the hollow wall sections are integral keyways which receive T-shaped anchors that also elevate the base member to allow for drainage. The anchors are slidable and can be selectively positioned for easy and secure installation. The base member, hollow wall sections, keyway and drainage areas can be integrally incorporated into a unitary device.
