A fence gate assembly comprises an upright having a longitudinal opening and a lateral opening. The assembly also includes an insert received within the longitudinal opening and coupled to the upright. The insert also includes a support portion extending from a rear wall. The assembly further includes a rail at least partially received within a cavity of the insert, the rail including a channel configured to at least partly receive the support portion therein.

The present invention provides a self-assembly safety door comprising: a doorpost coupled and fixed to both sides of a temporary doorframe formed on a distal end of a wall body; a door provided on the doorpost to horizontally rotate so as to be selectively opened/closed; a corner part provided on one end part of the door to be coupled to the door and hinge-coupled to the doorpost to rotate with the door at the same time; and a coupling part interposed between the door and the corner part to couple the door and the corner part.

A main tilting door for the closure of an access opening of a room includes two fixed uprights, including vertical sliding guides, and one fixed crosspiece associable with each other to define a fixed frame. The door includes two movable uprights and two movable crosspieces associable with each other to define a movable frame. The door includes tilting movement device/unit/component/apparatus or the like including two lateral supporting arms each having a first end which can be hinged to an intermediate area of the movable uprights and a second end which can be hinged to a top of the fixed uprights; and two sliding supports movable along the vertical sliding guides. The door includes panels associable with the movable frame. At least one of the movable uprights and the movable crosspieces includes a sliding track and cursors movable along the sliding track, the panels associable with the cursors.
