A walkthrough device may include a first component having a sleeve coupled to the first rail and a pole a pole slidably coupled to the sleeve between at least two positions including a retracted position and an extended position. In some embodiments, the sleeve may be fixedly coupled with the first rail and intended to remain attached (e.g., not intended for removal by a user). In another embodiment, the first component may be removably attached to the first rail so that a user may utilize and employ the device, and subsequently remove it, as desired.
