RAM® Safe-N-Secure™ Locking Knob Kit for Swing Arms & RAM® Tele-Pole™Until now, locking features on universal laptop holders have been hard to use or simply get in the way of typing. RAM has made all that just a memory with the new RAM SAFE-N-SECURE locking feature. Purchase your laptop mounting system with this option, add it on later, or integrate it into your existing system. No matter what you choose, you'll have one of the best theft deterrents available to keep your laptop where it belongs, with you. Using keyed locking knobs, this system operates easily and does not detract from the overall versatility you've come to love in your RAM Laptop Mount. The three locking knobs allow you to disengage the screwing of the swing arm knobs found on the top of the tele-pole, swing arm joint and laptop tray connection.
