D&D Technologies invented magnetic safety gate latches in the early 1990s. MagnaLatch® Child Safety Gate Latches are the safest and most trusted gate latches on the market. Designed specifically for toddler-resistant gates around swimming pools*, childcare centres, schools and homes, these Australian-made latches use patented magnetic technology and super-strong “permanent magnets” to eliminate mechanical jamming during closure. Made from hi-tech engineering polymers and stainless-steel components, MagnaLatch® Gate Latches are suitable for mounting to most gates and gate materials. Millions of the award-winning MagnaLatch® have been sold worldwide. This “Series 3” model of MagnaLatch® features a new, visible Locked/Unlocked indicator, rekeyable security lock (can be rekeyed by a locksmith to match doors), vertical and horizontal alignment indicators, and much more. It's been tested to 2 million cycles and it's 50% stronger than previous models. * When installing this latch to a swimming pool gate always confirm any safety requirements with your local Council or authorities to ensure compliance.
