[Video Update!] Introduction of the Folding Water Stop Board F-shield
We have added a video of the water stop test to the product page of the "F-shield Folding Water Stop Board"! In this video, we introduce the water stop performance tests of the "F-shield Folding Water Stop Board," assuming various scenarios. Please take a look. The "F-shield Folding Water Stop Board" from Furukawa Electric is a lightweight and simple water stop board and waterproof board that serves as an alternative to sandbags. It has approximately 15 times the water stop performance compared to sandbags. It can be easily assembled by placing it on the ground, opening it, and locking the fittings, making it a lightweight water stop board that can easily prevent flooding damage from typhoons, floods, and sudden heavy rains. When folded, it becomes as thin as 80mm, allowing for space-saving storage in narrow places such as shelves, entrances, garages, and warehouses. The water stop boards can be connected to each other, and the connection points allow for a maximum width adjustment of 50mm and an angle adjustment of ±5°, making it adaptable to various widths and shapes of openings. 【Features】 ■ Leakage amount: Approximately 200L/(h·m2) *This is not a guaranteed value but our test result ■ Lightweight at 5.8kg per piece (5.3kg for end pieces) ■ Can be installed for 10m with just one person in about 10 minutes ■ Reusable and long-lasting ■ No special construction required, and disposal is easy
