How a Barbed Wire Gate Closer Works

We use it every day, but we often take for granted our gate closer. Gate closers are valuable tools especially because they function to keep our gates closed. Without gate closers, we would always have to check every time we open the gate whether we have closed it properly. Gate closers work by closing the gates automatically once we get into our lawns. Another function of gate closers is that they make it easier for us to open our gates, even if our barbed wire fence is made of really heavy fence posts. In order for us to appreciate our gate closers even more, we need to understand the mechanism that drives their functions.

Kinds of Gate Closers

Gate closers exist in 2 kinds: surface mounted and concealed. Surface mounted gate closers are attached directly on the surface of your gate. On the other hand, a concealed gate closer is hidden within your gate. Barbed wire gate closers commonly exist as surface mounted gate closers.

Gate closers can also be classified according to their function. Gate closers can either be manual or automatic in nature. Manual gate closers are more popular among homeowners than its automatic counterpart.


A manual gate closer uses the principles of compression and torsion spring. When you open the gate, you generate energy which is then stored in the torsion spring of your gate closer. This energy is used for the closing mechanism of your gate closer. This is the main reason why you don’t have to push your gate to close it once you’re already in. The gate closer harvests the energy that you’ve exerted when pushing the gate. And when it comes for you to close the gate, your gate closer redirects that energy so that you no longer have to do the closing yourself.

Opening Mechanism - Gate closers are also helpful when it comes to opening heavy gates. The secret to that function is in the ability of certain gate closers to accommodate adjustments in the spring tension. When there is intense spring tension, it’s going to take you a lot of force to open the gate. At the same time, your gate will be banging itself shut. But if the strength of the spring is lessened proportionately, you will be able to open your gates with more ease and less force.

Closing Mechanism - There is nothing more annoying than a gate that generates a lot of noise when closing. Three valves are in charge of regulating the gate closer’s speed of closing. These 3 valves exert a delayed action on the gate closer. The latch speed is the speed of closing the door during the last third of its travel. The latch speed is often set really fast so that there is enough momentum for the gate to be latch closed. The sweep speed is the speed of closing the door during the earlier 2/3s of its travel. The sweep speed is often slow. If you want to lengthen the closing time of your gate, you can always make use of the third valve which controls the general delayed action.
