Door Dam G3 - Floor Threshold Seal Black
Prevents water pooling inside your garage





Cleverseal Door Dam G3 is designed to divert rainwater and prevent water ingress. Its innovative construction features durable, hard-wearing aluminium, enhanced with two continuous PVC cup seals. These seals compress firmly against the garage floor, forming an immediate, tight barrier to stop water from entering and causing flooding.
The superior quality of the Door Dam G3 ensures long-lasting durability—built to withstand years of vehicle traffic. Pressure-tested to endure loads of up to 25 tonnes, it’s ideal for environments with heavy machinery and frequent vehicle movement.
Now reinforced for commercial-grade performance, Door Dam G3 offers a reliable solution for both residential and industrial applications.
