OEM Development Case for Building Fixtures: Door Edge Opening Limitation Kanamono [Safety Stopper]

Maintains sash performance! No special processing such as notches is required, and it does not disrupt the harmony of the interior.

With the increase in high-rise living spaces and the expansion of openings, falls involving young children have become a social issue. In response, our company has devised an opening restriction at the sash edge. This allows us to maintain a consistent opening restriction amount regardless of the sash width. Additionally, a simple stopper is placed at the tip of the arm, enabling the temporary retention of the sliding door in the restricted opening state, thus achieving both fall prevention and natural ventilation. Furthermore, installation on the sash does not require any special processing such as notching, and can be done easily with just screws. 【Background and Issues】 - The increase in high-rise living spaces and the expansion of openings have made falls involving young children a social issue. - Conventional opening restriction devices mainly regulate the angle at the bottom frame of the sash, causing the opening restriction amount to vary depending on the sash width. - Customization to fit sash sizes is often required, leading to higher costs. *For more details, please refer to the PDF materials or feel free to contact us.*
