Designed to be surface-mounted to the gate and frame, these easy-install gate latches are available with or without the key-locking feature, and are designed to automatically lock when the gate is closed. This is achieved by using strong magnets in the keep in order to pull the bolt across when the lock lines up with the keep (when the gate is closed). In order to ensure the magnetism is sufficient to automatically lock, the distance between the main lock body and the keep should not exceed 8mm.
Ideal for DIY installations, these can be fitted in just a few minutes to almost any gate offering a frame and post of as little as 25mm (approx. 1"), and offer an impressive 10mm of horizontal and vertical adjustment to ensure that correct alignment can be achieved. To compliment this easy-to-fit design, these are also fully reversible so there's no need to worry about ordering the correct handing, as there's nothing in the design that dictates which way around it is installed.
It is important to note that while these have been designed with gates in mind, there are a whole range of applications where this could be an ideal solution. Anywhere you might consider a barrel-bolt or drop-bolt, these could potentially be considered instead, as an automatic solution. So whether it's to secure your attic hatch, or to secure the top and bottom leaves of a stable door, there's a wide range of potential uses for these auto-locking bolts.
In terms of build quality, a tough and hard-wearing polymer has been used for the body, which of course mitigates concerns of rust / corrosion. In fact, it is only the bolt itself (and the keyway on the locking version) which is metal, so routine maintenance could not be simpler.
Included with the lock are four self-tapping screws to allow these to be fitted to a wide range of gates, four cover-caps to cover the screw holes once fitting has been completed, and on the locking version you will also receive two keys.
The manufacturer recommends this be fitted horizontally as demonstrated in the images. We have found that the magnet is strong enough that it can lift the bolt vertically, so if you had a unique application where it needed to be fitted overhead, it does appear to be possible, and similarly the bolt will also hold itself up if used as a drop-bolt. However, using the MagnaLatch it in this way has not been recommended or documented by the manufacturer.
