Figure 2.2.7.13 — HAC S EDGE dimensions, section and elevation view. HAC S EDGE C has rebars that are located one rebar diameter below the
bottom base of the anchor channel profile to avoid clashing with the rebars
of the opposite corner channel (HAC S EDGE). The plate is taller and thicker.

Minimum substrate requirements for HAC EDGE Lite, HAC EDGE, and HAC S EDGE
Similarly to HAC, the minimum edge distances for HAC EDGE are established via testing. Although the HAC EDGE product line are
not implicitly covered in AC232, AC232 provides testing protocols for anchor channels to establish the minimum edge and corner
distance for the minimum member thickness. The following substrate requirements have been established in accordance with
testing protocols of AC232.

Corner and edge distances are measured to the center of the anchor.

Minimum edge distance for anchor channels in composite slabs
The minimum edge and corner distances for HAC EDGE are
consistent with the minimum requirements of HAC. In response
to the market trends such as composite slabs with pockets, Hilti
has added HAC EDGE with shorter anchor lengths.
For composite slabs where there is a pour stop along the
perimeter of the edge of slab preventing oxygen from reaching
out to the bottom of the slab and concrete cover of the anchor is
not required, the minimum member thickness can be reduced.
Chapters 8 and 9 provide design information for HAC EDGE in
composite slabs and how to account for the potential negative
influence of the metal deck.
Edge distance (c
a1
) is measured from the face of the slab (outer face of
the EDGE Plate).
