Jack Chain

Jack Chain

A jack chain is a type of chain that is constructed of thin wire and has links that are formed in the shape of an eight. It comes in a range of diameters, lengths, and load capacities.

The jack chain may be produced either as a single or double jack chain. So, there are two types of jack chains available on the market known as ‘Single Jack Chain’ and the ‘Double Jack Chain’.

Single Jack chain is made out of weldless links that are bent in a figure-eight pattern to form a loop.

Double Jack chain is formed in the same way, but the lower loop is made up of two strands of wire rather than simply one as in a single jack chain.


Single Jack chains are not weak because they are weldless. Some chains have a weight limit of hundred pounds, even though they are weldless.


Jack chains are typically made with metals such as steel, plain carbon steel, alloy steel, brass, silver, and gold. But, in some cases, plastic types such as HDPE (High-Density Poly Ethylene) are used to make jack chains.

Applications of Jack Chain

Jack chains are often used to hang lights, boards, artwork, and signage safely.

It’s economical and adjustable, making it appropriate for a wide range of linear and high bay fixtures.

When lavatory cisterns were located near the pan, jack chains were frequently employed to release the cistern plug.
