A railing system comprising:

• first and second rails;
• one or more posts, each of the one or more posts comprising a post surface;
• a first bracket connecting the first rail to one of the one or more posts, the first bracket comprising:
• a first plate adapted to be attached to the post surface;
• a first pivot member extending from and attached to the first plate, the first pivot member comprising first upper and lower surfaces, wherein the first upper surface comprises a first upper opening and the first lower surface comprises a first lower opening, and wherein the first upper opening and the first lower opening are aligned;
• a first receiving portion adapted to receive one end of the first rail, the first receiving portion comprising first sidewalls and a first cover, wherein the first cover comprises a first cover protrusion adapted to engage with the first upper opening;
• and
• a first base connected to the first receiving portion, the first base comprising a first base protrusion adapted to engage with the first lower opening;
• wherein the first receiving portion and the first base are adapted to pivot about a longitudinal axis of the first pivot member to adjust a first angle between the first rail and the post surface;
• and
• a second bracket connecting the second rail to the one of the one or more posts, the second bracket comprising:
• a second plate adapted to be attached to the post surface;
• a second pivot member extending from and attached to the second plate, the second pivot member comprising second upper and lower surfaces, wherein the second upper surface comprises a second upper opening and the second lower surface comprises a second lower opening;
• a second receiving portion adapted to receive one end of the second rail, the second receiving portion comprising second sidewalls, a second cover, and a second base, wherein the second cover comprises a second cover opening and the second base comprises a second base opening, and wherein the second cover opening, the second upper opening, the second base opening, and the second lower opening are substantially aligned;
• and
• a pin extending through the second cover opening, the second upper opening, the second base opening, and the second lower opening;
• wherein the second receiving portion is adapted to pivot about a longitudinal axis of the second pivot member to adjust a second angle between the second rail and the post surface.
