HAC-T S EDGE C has reinforcing bars that are located one reinforcing bar
diameter below the bottom base of the anchor channel profile to avoid clashing
with the reinforcing bars of the opposite corner channel (HAC-T S EDGE). The
plate is taller and thicker.

Min. substrate requirements for HAC-T EDGE Lite, HAC-T EDGE, and HAC-T 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..
Minimum edge distance for anchor channels
in composite slabs
The minimum edge and corner distances for HAC-T EDGE are
consistent with the minimum requirements of HAC. However, as
a response to the market trends, composite slabs with pockets,
Hilti has added HAC EDGE-T with shorter anchor lengths.
For composite slabs where there is a pour stop along the
perimeter of the edge of slab prevent, prevent oxygen from
reaching out to the bottom of the slab, the minimum member
thickness can be reduced.
Chapters 8 and 9 provide design information for HAC-T EDGE in
composite slabs and how to account for the potential negative
influence of the metal deck.

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

Edge distance (c

) is measured from the face of the slab (outer face of the EDGE
Plate).
