Standard connection links pin two ends of chain together to make a loop. Each end of the chain needs to end with a “narrow” link section. The link is held together by a clip that sits in a groove on the two connector pins.
Also called a Offset Link is for applications where one more link is too long, and one fewer link is too short. A half link connects a “narrow” link section to a “wide” link section. The link is secured with a cotter pin.
1.5 Link:This connects to two “narrow” link sections using two connecting links, but adds an additional half link section to the overall length. Use this to eliminate the potential failure point of a cotter pin connection.
These are useful links to add mounting points to your chain. Add the K-link to your chain path and bolt or rivet the link to the element you want to move to create an elevator or conveyor.
