Heads Up Lock Co. (www.headsuplock.com) has just released a new model of alert light that lets outside viewers know when the restroom is in use in several different rooms. Called the Parent/Child, it has most of the features the existing models have but is now geared specifically for viewing in 2 or more locations. The eye pleasing LED’s show room availability.  It saves time and embarrassment of having to stand in front of the restroom door and wait. No more guesswork or wasted time. Workplace productivity goes up along with employee morale. This convenient device can be used for single stall restrooms. The kit comes complete with everything a qualified handyman will need to install. It can also be used in restaurants, and office buildings to name a few. The lock is ADA certified and Made in the USA.
