Abstract
A temporary sign holder utilizes a clamping member attachable to a rail to support a sign post in an operative location. The clamping member is formed with two hooked shaped members that are tightened around the base of the rail from opposing sides. One of the hooked members has a threaded rod extending through a sleeve on the other hooked member with a locking ring threaded onto the rod to provide a tightening arrangement. A horizontal member extends outwardly from the hook shaped members. This arrangement enables the hooked shaped members to be pressed inwardly towards each other towards the rail web to provide a heightened degree of clamping force capable of resisting vibrational and other forces that occur as a result of train passage. A lock prevents unauthorized loosening of the locking ring to create a tamper-proof structure.
