Apparatus and associated methods relate to a safety interface plate element that securely attaches to a length of webbing, and further provides a plurality of non-intersecting apertures to couple to a corresponding plurality of safety devices. In an illustrative example, the safety interface plate element may include a slotted opening through which the webbing is threaded. In some examples, the webbing may be removably installed in the slotted opening via a gating mechanism. In some embodiments, the safety interface plate element configured with an embodiment of the gating mechanism may be retrofit to a closed webbing on a pre-fabricated safety harness, for example. In various examples, multiple safety devices may be securely coupled to a safety harness via embodiments of the safety interface plate element.
