Series 526 Impact Installation Instructions
Stretch the anti-walk block out as flat as possible, and insert it in between the glass and
frame so that it opens up inside the glass pocket at midspan of the D.L.O. at the deep
pocket. See figure 50 below. This can only be done from the drive-in gasket side of the
frame. After the deep pocket anti-walk block is installed, slide the glass unit over against
the anti-walk block, and insert one into the shallow pocket at midspan of the D.L.O. If
Necessary, re-center the glass unit to maintain equal glass bite all around.
