D&D Technologies invented magnetic safety gate latches in the early 1990s. The Australian-made MagnaLatch® Safety Gate Latch uses magnetic technology to produce a latch that is toddler resistant, safe and reliable. The MagnaLatch® Alert is the newest model in the MagnaLatch range. It's a combined gate latch and gate alarm in one, convenient product. The Alert sets entirely new levels for gate safety around swimming pools, childcare centers, schools, homes or wherever child safety is critical. The MagnaLatch® Alert offers dual electronic warnings: bright, flashing LED lights, and audible alerts that sound if a gate is opened or left unlatched. You can see at a glance, and hear from a distance, if your gate is not secured. A single beep upon each entry or exit of a gate notifies of family, friends or intruders.
