An extension bar is an attachment that fits between a handle and a socket, such as a socket wrench or ratchet handle. Extension bars are available in various lengths, from short to long.
Extension bars are used to reach bolts and nuts in places that normal sockets cannot reach. If the extension bar itself cannot reach the part, it can be extended by adding an additional extension bar.
The extension bar is attached between the socket and the handle. The method of attaching and detaching is the same as that of the socket.
If the extension bar has an anti-lock function, release the lock and attach or detach the extension bar. If the extension bar is not equipped with an anti-locking function, pull the extension bar to remove it, and push it in firmly to install it.
Two or more extension bars can be connected together to make a longer extension bar. However, care must be taken to avoid wobbling. This can increase the escape of force, and can also lead to disaster if the extension bar comes off.
Length is the most important factor in choosing an extension bar. If it is too short, it will not reach the bolt or nut you want to attach or detach, making it pointless to install. However, if it is too long, it can also be problematic. When is too long, the extension bar will tend to flex, which will cause it to lose power. Also, if you are working in a confined space, you may hit your hand against a wall or a piece of equipment when you turn the handle. To work safely, it is necessary to choose an extension bar that is neither too long nor too short.
One type of extension bar is one with a swivel function. This is used when you want to use the extension bar at an angle. However, since the direction of rotation of the screw and the angle at which the handle is turned are misaligned, it cannot exert very strong force. Another type has knurling on the shaft part, which allows fast turning by turning the extension bar directly with the fingers when the ratchet handle is used.
