Cautionary Points for Installation

Proper installation will ensure use of the product under optimal conditions. Please note the following points during installation.

Floating If sand or other debris enters into the side of U-Jiro during heavy rain due to the ground condition and so forth, U-Jiro may float. Floating can be prevented by fixing a board outside on the bottom surface.


Strong Earth Pressure If the earth pressure is strong, U-Jiro's sides may bend inward slightly. In these situations, it is recommended to fit a steel grating or wooden block.
