What Is A Pin

Locks already existed in ancient times, when they were still made of wood. Nowadays, most of the pins in circulation on the market are of metal or stainless steel type.
1. A pin is usually composed of two parts. One is the plug-in rod fixed on the storefront that can move horizontally left and right, and the other is the plug-in ring fixed on the door frame, both in the same horizontal position and corresponding to each other. The function of the insertion ring is to prevent the door from being opened and has a certain anti-theft ability.
2. Pin can also be divided into two types: visible pin and hidden pin. The most obvious difference between the two types of plugs is the issue of size. Because the difference in size determines the price of the pin and the overall difficulty of installation. According to the market situation, the price of the Mingpin will be relatively more affordable, and its installation will also be convenient. As for the hidden pin, it is more reliable in function and has better anti-theft ability than the exposed pin. It takes a lot of effort to pry it open, and even installation needs to be done by professionals.
3. The size specifications of sockets are generally around 75mm-300mm and can be divided into 2-5 inches, with a maximum of 12 inches. Common plugs are generally made of stainless steel, aluminum alloy, and zinc alloy, which have excellent corrosion resistance and durability. Before making a purchase, it is essential to measure the relevant dimensions of your own doors and windows.
