Assembly:
Gluing is optional. User some wood glue or hot melt glue to assemble in the order of 1 + 4 + 2 & 3 + 4+ 1. Use 1″ machine screws to assemble. Adjust the thickness of the paper for the gasket as it/they will help the gate to open smoothly.

Use hot glue or use other adhesives of your choice to adhere the pipes (min. 4″) directly to the holes. Urethane glue will be a good permanent solution.
