The present invention relates to devices and methods for suspending and retaining telecommunication cables, power cables, and other items within or outside of a building. According to certain embodiments of the present invention, devices are provided for supporting, suspending and retaining an article within or outside of a building, such as telecommunication cables, power cables, and other items. The devices generally comprise a support tray having a bottom plane and top plane, whereby the tray is adapted to support the article. The tray will include at least one corner area, but may include many separate corner areas. According to these embodiments, the devices will further include a retention device, which is affixed to or integrally formed with the corner area. The retention device will preferably include at least one protrusion which extends from the corner area into an interior portion of the tray. The invention provides that the retention device and, more specifically, the at least one protrusion will be effective to prevent articles, such as telecommunication cables, power cables, and other items, from being pulled over the corner area of the tray during installation of the cables.
