Mortise lock in the gate - choose and install

Today, the lock on the gate has become not only a decorative element “from drafts”. This is a necessary precaution against unauthorized entry, so you need to choose high-quality and functional locking devices.

And how can you choose it correctly and install it securely with your own hands, without turning to experts? Follow some rules and listen to the advice of professionals.

Let's try to give a complete and plausible concept of what a quality mortise lock for the gate, and what you need to put it on any canvas yourself.

Mortise lock

Basic concepts

At the gate in the fence always have a large impact force. The fence itself is stationary, and the gate all the time, moving, opening or rolling. Mechanics are always under the influence of dynamic loads, parts wear out, rust and become unusable.

So, you need to choose high-quality locking devices that will not break at the most inopportune moment. These should be durable products, preferably from leading manufacturers, who have already been able to recommend themselves with the quality and durability of the product.

And not only the reliability here is at the forefront. If you don’t get into the courtyard, it’s still half the problem, but if an intruder gets there, it’s not good.

Therefore, the dead lock of the gate must also meet safety requirements and have a high level of protection. The simplest locking device can, with a certain ability to open a nail.

Tip: in this case: even a simple mortise lock for the gate must be fixed in a special “case”, which is made of metal. So he will not only be "vandal resistant", but moisture will not get into it.

By the way, the reason for the rapid release of the mechanism is the moisture, and even the dust that falls inside the case. So the protective cover is still needed.

If water gets inside, in winter you risk not opening the gate at all. Pick up waterproof materials and keep the case tight.

Choice: Is it a problem?

If you know what to choose and how - no problem. Another thing is that consumers today are looking more at price and appearance than at functionality and quality.

Therefore, we are immediately talking about what should not be acquired. The most openable and very unreliable are padlocks, then the list - slatted (for more details, see How to open the front door without a key)

A hacker will need about a minute or less to open them. Not very reliable and mechanisms with a cross key or cylinder. And, of course, you never need to buy homemade options.

It is mortise locks for the gate will be the right choice! They are tightly embedded in the sash, fastened with a face plate, and it also serves as a guide for the bolt.

Picking up the locking device, on the bolt and pay close attention: see if it fits well to the body, measure its thickness (must be at least 2.5 mm).

Such detail provides for the lock model durability and reliability. The deadbolt should be made of rods-cylinders, which are scrolled around the axis, they are almost impossible to cut, the canvas just slips when the cylinder rotates.

Installation

The lock inset into the gate is also a technological process, which has its stages and nuances. If the gate is metal, and profile pipes (usually rectangular) are used as the frame, then the locking device should be selected to fit the existing size (see How to make a wicket from corrugated board and profile pipe). That is, it is necessary that the lock fit normally into the cavity of the frame tube.

Now among the proposals there are special locks designed specifically for such purposes. If you buy such a device with a full set of the rest of the above functions and characteristics, the rest of the technology works almost no different from the banal installation of an interior lock.

Working process:

1. At the gate at the end of the frame of the profile mark the place of installation of the future lock and sawn with the help of angle grinders (angle grinder, "grinder" in a scientific way) rectangular groove. Dimensions - 1 mm larger on each side than the rear end of the lock. At the same time, do not saw through the corners if you have a cutting disc on a large-sized grinder. Then modify them with a small angle grinder with a small circle diameter. And if you immediately take a small machine - there will be a lot more labor costs, since the thick profile will be sawed for a long and difficult time.
2. Insert the lock into the prepared rectangular groove, then screw over its attachment points. Self-tapping screws are not used here, therefore, for fixing, drill holes that are a millimeter smaller in diameter than fixing bolts. Then in the received openings with a tap you will cut a thread. And still, it is too early to fasten the lock, although it is necessary to install it in its place.
3. With the lock inserted into the place prepared on the gate, you can close the sash. Measure and mark the place for drilling the hole under the larva. This stage requires special care, since an error of one to two millimeters can cause the device to not lock, and despite all the locks, the gate will not close. Maximum - pretend to swing open at the slightest push.
4. Similarly drilled or sawed grooves under the larvaIf there is an additional fixing plate on the frame or support bar, this is true if the pillars on the sides of the wicket are wooden. In the steel profile will be enough one slot.
5. Next, the hole in the gate is carefully and carefully drilled to install a square connecting rodOn which handles on one or two sides are attached, depending on the design of the locking device. Sometimes it is advisable to not install the handle from the outside at all, respectively, and there will be no need for drilling holes. It turns out that the exact location of the castle is not visible from the outside, which complicates the process of unauthorized opening.
6. Drill and prepare all the grooves and holes, you can embed the lock into the gate and hold it. Also installed and fixed reciprocal plate.
7. After installing the square rod handles are put on itUnder which special linings are sometimes installed (also provided for the product package). Pads are tightened, the handles are fixed.

If your fence is made of profiled sheeting, and the wicket frame is made of thin profiles (see the wicket from the profile pipes together with the gate), you must first make a “pocket” or a box, weld it at the right level, and then install the dead lock on the wicket.

In this case, the thickness of the lock does not matter, since the box can be made of any size. The rest of the technology is the same.
