Hi, I'm JJ Bock, Director of Operations for Rubber-Inc. Welcome to another episode of In Stock With Bock. Today, we're checking out a simple little product that can catch a big problem before it happens. Literally, before a wheel comes loose. The Checkpoint Wheel Nut Indicators by Martins Industries. The idea behind the Checkpoint is simple but genuinely smart. If you install these on your wheel nuts, lining them up in a recognizable pattern around each wheel, if a nut ever starts to loosen and rotates just a little, that pattern breaks and it's immediately recognizable.

No tools, no guesswork, just a quick glance that tells you something's moving that shouldn't be. These are available in various sizes, colors, and styles, including a standard and a high temp option. In addition to this, the Martins Checkpoints are biodegradable wheel nut indicators, which is a safety product that's also eco-friendly. This is the kind of product that safety-conscious shops love because it's inexpensive, simple to use, and turns a routine walk-around inspection into a real safety check. That's a wrap for this episode. Please reach out to your local Rubber-Inc. account manager or visit us at www.rubber-inc.com to get yours today. Thank you for watching another episode of In Stock With Bock, we'll catch you next time.
