Circular waterway jump prevention connecting manhole cover "Jointer"

Easy, safe, and soundproof! Simple installation by connecting the main body and fitting it into a concrete groove. Installed in concrete precast products and circular waterways.

We would like to introduce the "Jointer" <for circular drainage channels, insert type> handled by Okagreat Co., Ltd. The "Jointer" is a splash-proof connecting cover for circular drainage channels that does not require bolt fixation. The main body is lifted and the connecting parts are crossed and connected. After connection, there are no gaps even when the main body is stretched or bent. After connection, it allows for linear extension of about 12mm on one side, and can be installed without gaps even in curved sections. Additionally, there are various types available, including steel galvanized grating type, stainless steel type, checker plate type, and patterned plate type. 【Features】 ■ Easy installation by simply connecting the main body and inserting it into the concrete channel ■ Allows for linear extension of about 12mm on one side after connection, and can be installed without gaps even in curved sections ■ Fixed to the concrete by the bumps on the side of the main body, ensuring effective splash prevention and noise reduction measures *For more details, please refer to the PDF document or feel free to contact us.
