A first channel-shaped elongate member is secured to a wall, which may not be vertical, and a second elongate member incorporating a part-circular door post 3 is secured within the first member by pinch bolts 29 after adjustment to vertical. The door 8 rotates on a pivot rod 4 inside the door post and includes part-circular walls which rotate inside the post. The walls contact abutment surfaces inside the post to define the limits of pivotal movement of the door 8. The lower edge of the door carries a sealing strip which flexibly extends into the door post and is secured thereto by a headed pin 16. <IMAGE> |
