Rail mounting systems and methods

A rail system for mounting on a vertical support, the system comprising:

• a) a rail assembly having an end portion and including:
• a reinforcement rail;
• and
• a polymeric sleeve at least partly surrounding the reinforcement rail;
• b) a metal bracket defining a rail cavity adapted to receive the end portion and adapted to secure the rail assembly to the vertical support, the bracket including:
• a rear wall;
• a pair of opposed side walls extending forwardly from the rear wall such that the rear wall extends between the side walls;
• and
• at least one support fastener opening defined in the rear wall between the side walls and in communication with the rail cavity, the at least one support fastener opening being adapted to receive a fastener to secure the bracket to the vertical support;
• and
• c) an angle adapter, the angle adapter comprising:
• a front face adapted to engage the bracket;
• and
• a rear face adapted to engage the vertical support and forming an angle of less than 180 degrees with the front face;
• wherein:
• the angle adapter includes a locator projection extending from the front face;
• and
• the bracket defines a locator hole therein adapted to receive the locator projection.
