Series 526 Impact Installation Instructions
The setting block for standard frame horizontals is HEP0. The door headers require the use
of a HN13 setting block. Two setting blocks per D.L.O. are required and should be placed at
1/4 points or 1/8 points, depending on special dead load requirements. Depending on the
size and configuration of each DLO, the glass setting blocks must be placed to give the best
support of the glass without adding dead load weight to deflect the horizontal. Figure 36
below shows typical 1/4 point and 1/8 point setting block locations.
Contact EFCO Structural Engineering for blocking requirements, other than 1/4 and 1/8
points.

Customer / Installer Note:
EFCO setting blocks are typically 4" in length with
different depths. If the glazing infill is "NOT BY
EFCO" and glazing sizes are larger than 40 square
feet, the glazing details must be reviewed by the
glazing manufacturer for proper setting block size.
