A fiber optic closure includes optical adapters located within an enclosure, a ledge located within the enclosure between the optical adapters and a cable port, and a strain-relief bracket located within the enclosure at the ledge. The strain-relief bracket defines channels that align with channels defined in the ledge. Each of the channels of the strain-relief bracket is narrower than a fiber optic connector that is suitable to be plugged into one of the optical adapters. The strain-relief bracket provides support ledges between the channels that inhibit fiber optic connectors from being pulled out of the optical adapters.
