Gates is proud to introduce another resource for designing belt drives and/or calculating installation tension. You may be familiar with Design Flex Pro or our previous Web version, but now Design Flex Mobile is available. Design Flex Mobile bridges the gap between our web based software and phone app, PT Toolkit. Unlike Design Flex Web, this mobile version can be accessed on ANY device connected to the internet. And unlike Design Flex Pro, no download is required. Check it out today by going to www.gates.com/dfmobile from the browser on your device.
