Ultimate Water Leak Protection for Your Smart Home

Introducing the AJAX WaterStop, a smart, remotely controlled water shutoff valve designed to integrate seamlessly into your AJAX security system. This device provides peace of mind by automatically shutting off the water supply in as little as 5-7 seconds upon detecting a leak, preventing costly water damage. The WaterStop combines a high-quality Bonomi Industries valve with a powerful electric actuator, all controllable from anywhere in the world via the Ajax app. You can also set up automation scenarios to shut off the water at specific times or when you arm your security system.

Robust Design and Reliable Performance

The AJAX WaterStop is built to last, featuring a durable brass valve that is compatible with both hot and cold water pipes. Its powerful electric actuator delivers up to 8.5 N·m of torque, ensuring it can shut off the valve even if it's stuck. The device operates on pre-installed batteries with a life of up to 3 years, and also has the option for an external power supply. For manual control, there is a button on the actuator and a lever on the valve itself.

Advanced Wireless Technology

Utilizing AJAX's proprietary Jeweller radio communication technology, the WaterStop ensures secure and reliable two-way communication with the AJAX hub at a range of up to 1,100 meters in open space. This advanced protocol uses block encryption and frequency hopping to prevent sabotage, spoofing, and data theft, providing a robust and tamper-proof connection.

Great Cargo Net for the Price! 👍
This item is nice and appears to be high quality compared to others that cost way more. So for $15 you cannot ask for better. Now how it holds up over time is another story. My last one was so dry rotted and it stayed stored inside the pocket of my door for several years. Regardless for only$15 if you get 1 year out of it you got your money's worth. Just purchase a new one. As far as seams, stitching and elasticity, it's very good. Carabiners are black coated what looks and feels like aluminum but cannot confirm. The quality as they open and close feel solid. Again time will tell. I would definitely recommend this net. The only negative is the bag it comes in is garbage and cheaply made. It's like dollar general plastic toiletries bag.

Very handy in many situations.
This is a very useful gadget. It is very stretchy, adjustable with extra straps, easy to store in it‘s own bag and a pretty good weight. We used it to transport a mattress, hay bales, a large stack of cardboard boxes and a desk. The hooks are strong but easy to open, it did not tangle for us at all.

Cheap and tough
I got this for a trailer not a truck and it works perfectly for dump runs instead of using a tarp and bungies. Comes in a little bag I'll never use again and had some accessories i don't understand, but if you want a springy net for something that's cheap enough not to care about breaking this is your product
