b, the configuration without hanging weight;

c, page open door, open the first page under the section of the door, then open the page on the festival door, opening angle, while greatly reducing the water thrust the door open page, reduce energy loss.

d, page close the door when the door section on page to close, the next page and then close the door section, greatly reduces the door when the door closed block pages based on impact force.

Double pontoon-door installation:
