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.
units
Hilti Anchor Channel Rebar Face of Slab with smooth channel
lips (HAC CRFoS U) are offered in three channel profile sizes;
HAC-50, HAC-60, and HAC-70. Hilti Channel Bolts C (HBC-C)
are suitable for all HAC CRFoS U.

*Custom rebar lengths can be offered upon request. Longer rebars may require longer lead times. Refer to sections 2.4 and 2.6
for information about lead times of custom channels.
