Figure 2.2.4.1 - HAC CRFoS profiles with matching channel bolts.
The standard portfolio consists of HAC-50, HAC-60, and
HAC-70 channels profiles with pre-defined channel length, rebar
lengths, number of anchors, and defined rebar diameter. Non-
standard anchor channels (i.e. custom channel length, rebar
length, number of rebars etc.) can be provided upon request.
Refer to sections 2.4 and 2.5 for additional information about
standard items and lead times.
