A rail apparatus that is attachable to a support surface such as a set of telescoping bleachers and is capable of remaining attached when the support structure is in either an extended, open position or a retracted, closed position. The rail apparatus has a P-shaped handle portion integral with a shaft element that is connected to the support surface through a mounting system having a support socket and spring system. The mounting system is connected to the support surface either on the front, top or side thereof. The spring system is inside the lower portion of the shaft and provides a force that keeps the handle portion of the rail apparatus in place within the support socket, yet allows for the handle pardon to be rotated to various other positions if desired. When the position of the rail apparatus is changed, the spring system is compressed, the rail apparatus moved and the spring system is then decompressed and allowed to once again apply pressure and keep the rail apparatus in the selected position within the support socket. The mounting system allows for the rail apparatus to remain connected to the support surface whe n it is in either an open, extended position or a closed, retracted position. The rail apparatus also has a rear support attachment that can be attached to the underneath side of the support surfac e as well as the support socket to provide added support and stability to the rail apparatus.
