What is the Strap Sentry?

A strap tension monitoring device for anyone who uses a strap and is worried about it coming loose while they are driving.Have you ever set out on a road trip with precious cargo secured by just a couple of ratchet straps and a sprinkle of hope? Whether it’s a freshly polished motorcycle, a stack of lumber for a home project, or a ladder on your roof, the nagging worry of a strap loosening with every bump and turn in the road is all too familiar. The risk isn’t just about your cargo falling into the road and getting destroyed—it’s also about protecting everyone driving around you.If you’ve ever found yourself constantly glancing at your side and rearview mirrors, distracted from the road ahead as you worry about your load’s stability, you’re not alone. That’s why we’ve engineered the Strap Sentry—the ultimate solution to ease your cargo-hauling concerns and keep your focus where it belongs: on the road.

This innovative device easily clips onto any standard 1 to 2 inch wide strap, transforming it into a smart, electronic guardian for your cargo. Using patented technology, the Strap Sentry measures strap tension in real-time, offering you peace of mind like never before.Our intuitive smartphone app syncs with all of your Strap Sentry devices to continuously monitor strap tension, ready to alert you the moment it falls below a safe threshold.

With the Strap Sentry, you can finally put an end to the stress and uncertainty that comes with traditional cargo hauling. Whether you’re transporting some of your cherished possessions or your essential work equipment, this solution transforms your hauling experience, ensuring safer roads, worry-free trips, and peace of mind on every journey.

How Does the Strap Sentry Work?

The Strap Sentry is designed to attach to any standard 1 to 2 inch wide strap and continuously monitor for shifts in tension that could indicate a loosening strap or a potential risk to your cargo.

Strap Sentry for 1 to 2 in strap

Once clipped onto your strap, the device seamlessly pairs with the companion smartphone app. As you drive, the app provides live updates and alerts, notifying you if tension drops below a safe threshold.In the app, you have the option to lock in your starting tension. This will easily allow you and the app's logic to judge how the real time tension compares to where you started out.If the strap is showing a trend of loosening, you will get a soft warning from the app. However, a more dramatic alert will be sent if the strap has reached an unsafe condition.

And don’t worry—you won’t need to constantly check the app. It works in the background, and will let you know if there is a problem, keeping an eye on your load so you can focus on the road ahead.

Who is the Strap Sentry for?

The Strap Sentry is designed for anyone who hauls cargo and values safety and peace of mind on the road.

By providing real-time updates and alerts, the Strap Sentry helps anyone transporting cargo—whether it’s for work, a hobby, or personal needs—travel with confidence and focus on the road, not on the load.

Hidden Dangers of Unsecured Loads

The Strap Sentry can help mitigate several risks associated with transporting cargo on roadways, including:

- Load Shifts and Falling Cargo: Unsecured or improperly secured cargo can shift during transit, increasing the risk of items falling onto the road. This can lead to accidents, property damage, and injuries. The Strap Sentry continuously monitors strap tension, providing real-time alerts if it drops below a safe threshold, so you can stop and readjust as needed.- Damage to Cargo: Shifts in cargo can cause damage to your transported items, especially if they are fragile. By ensuring that your straps remain secure, the Strap Sentry helps protect your belongings from getting jostled, scratched, or broken during transit.- Driver Distraction: Constantly checking rearview mirrors to monitor cargo can take your focus off the road. The Strap Sentry provides peace of mind with alerts through its app, allowing you to stay focused on driving while remaining aware of your cargo's security.- Legal Liability and Fines: Many regions impose fines for unsecured loads due to the risks they pose to other drivers. The Strap Sentry helps ensure your cargo is properly secured, reducing the chance of facing legal consequences.- Roadway Hazards: Fallen cargo not only endangers other drivers but can also create hazardous obstacles on the road, potentially causing collisions or damage to vehicles. By alerting you to strap loosening early on, the Strap Sentry can help prevent these hazards from materializing.

By addressing these risks, the Strap Sentry contributes to safer roads for everyone and provides an added layer of security for both your cargo and your journey.

Design Features

Connect Multiple Devices

When securing multiple items to your vehicle or trailer, it’s essential to protect each one effectively. With the Strap Sentry, you can pair multiple devices through our user-friendly app, allowing you to monitor each strap's tension independently. Each device maintains its unique starting tension, ensuring that all your cargo is equally protected and secure.

Quick and Easy Installation

At Strap Sentry, we understand that your hauling journey begins long before you hit the road. That's why we've thoughtfully crafted our product to seamlessly integrate into your existing routine, without adding unnecessary complexity or hassle. With our device, simplicity is key. Just clip the Strap Sentry onto your strap, connect with the app, and you're ready to hit the road. It's that easy.

Latch Locking Button

The last thing we want to do is add something else to worry about. That's why we've put a significant amount of engineering effort on how we secure the Strap Sentry to the strap. With this latch locking button, you can trust that it won't come loose or shift during transit. It provides an extra layer of security, ensuring the device stays firmly attached.

Locked In with a Gator Bite-Like Hold

Working in tandem with the latch locking button, the gently serrated edge on the lower housing grips the strap firmly, preventing any lateral slipping. Once installed, it stays locked in place, resilient against road vibrations, high winds, and more, much like the unyielding grip of a gator's jaw.

Intuitive LED indicators

The LED indicator array, behind the site glass, provides clear, intuitive feedback at a glance with four indicator modes.

Tension-Activated Sleep/Wake Functionality

Our smart device conserves battery life by entering sleep mode when not in use, instantly awakening and ready to pair the moment it detects tension.

Standard USB Charging

Stay powered up with ease, whether at home or on the road, with the Strap Sentry's standard USB micro B port, conveniently safeguarded by a rubber waterproofing cover. Its intuitive light indicators transition from amber during charging to green when complete, ensuring reliable power status at a glance. With the flexibility to charge at home or leave it on the charger in your vehicle, keeping your device ready for action has never been more convenient.

While you focus on the road ahead, the Strap Sentry will continuously monitor the tension in the background. The app will push a notification alert if it loosens too much.A single push notification alert is sent when the tension drops beyond the warning limit (default : 10% from starting tension).
