Carriers may be adapted, or configured, to secure one of a plurality of varying-sized devices received thereby. Regardless of the size of the device, an interface of the device may be positioned proximate an interface opening of the carrier for, for example, operable coupling to an enclosure. The carrier may include a first side rail, a second side rail, and a movable rail that moves between the first and second side rail to adapt, or configure, the carrier to secure the one of the plurality of varying-sized devices received thereby. For example, the movable rail may be linearly translatable between the first and second side rails.
