The tensile strength of these pipe hangers is therefore unknown which may lead to excessive stretch or deformation changing the proper slope of sprinkler piping. In the worst case, they may fail prematurely.

Figure 1 shows an authentic CCTF model A-100 1-1/4” swivel type pipe hanger (left) next to a counterfeit AU-100 1-1/4” example. The knurled marks on the swivel nut are rolled closer to the hanger on the counterfeit.

Figure 2 shows the authentic pipe hanger on the left and the counterfeit on the right. The authentic hanger has a larger swivel ring (indicated by the yellow arrows). The size marking on the authentic hanger uses a diagonal stacked fraction while the counterfeit is a standard horizontal style.

Figure 3 shows markings stamped into the authentic A-100 pipe hanger. The model designation marking “A-100” uses a stylized letter A. The UL/ULC Listed and FM Approvals markings are also included.

Figure 4 shows markings on the counterfeit pipe hanger. The model designation “AU-100” is stamped next to the counterfeit FM Approvals marking.
