13. A cable hanger, comprising:

a base panel;

a first arm having a proximal end and a distal end, the proximal end being attached to the base panel, the distal end comprising first locking projections configured to be inserted into an aperture of a structure, the first locking projections comprising a first contact surface;

a second arm having a proximal end and a distal end, the proximal end being attached to the base panel, the distal end comprising second locking projections configured to be inserted into the aperture of the structure, the second locking projections comprising a second contact surface;

a first shroud disposed along the first contact surface; and

a second shroud disposed along the second contact surface.

14. The cable hanger of Claim 13, wherein the first shroud comprises an interface between the first contact surface and the structure, and wherein the second shroud comprises an interface between the second contact surface and the structure.

15. The cable hanger of Claim 13 or 14, wherein the first shroud electrically isolates the first contact surface from the structure, and wherein the second shroud electrically isolates the second contact surface from the structure.

16. The cable hanger of any of Claims 13-15,

wherein the first shroud comprises a first inward surface and a first outward surface, the first inward surface having a first interference feature disposed thereon, the first inward surface being adjacent to the first contact surface, the first outward surface being configured to mate with the aperture of the structure; and

wherein the second shroud comprises a second inward surface and a second outward surface, the second inward surface having a second interference feature disposed thereon, the second inward surface being adjacent to the second contact surface, the second outward surface being configured to mate with the aperture of the structure.

17. The cable hanger of Claim 16,

wherein the first interference feature and the second interference feature are configured to assume a first aligned position when a load applied to the first shroud is approximately symmetric to a load applied to the second shroud, and

wherein the first interference feature and the second interference feature are configured to assume a second misaligned position when a load applied to the first shroud is asymmetric to a load applied to the second shroud.

18. The cable hanger of Claim 17,

wherein the first interference feature is configured to insert into the second interference feature in the first aligned position; and

wherein the first interference feature is configured to interfere with the second interference feature in the second misaligned position.

19. The cable hanger of Claim 16, 17, or 18,

wherein the first interference feature includes a projection, the projection having a length extending away from the inward surface, a width parallel to the inward receiving surface and perpendicular to the length, and a height perpendicular to the width of the projection and the length;

wherein the second interference feature includes a cavity, the cavity having a depth extending into the inward surface, a width parallel to the inward receiving surface and

perpendicular to the depth, and a height perpendicular to the width of the cavity and the depth; wherein the width of the cavity is greater than the width of the projection; and

wherein the height of the cavity is greater than the height of the projection.

20. The cable hanger of any of Claims 16-19, wherein the first interference feature includes a projection and the second interference feature includes a projection.

21. The cable hanger of any of Claims 13-20, wherein the first shroud is configured to be substantially identical to the second shroud.

22. The cable hanger of any of Claims 13-21, wherein the first shroud comprises at least two interference features and the second shroud comprises at least two interference features.
