These Are Awesome
I built a minibike and no matter what I tried, the chain was either too short or a link too long. If I removed the link on the long chain, then it was too short. I Tried adjusting the engine position, which was limited. Moving the rear axle around which was limited too, nothing seemed to give me that perfect tension. I came across these offset links. They saved me from the frustration. The chain that was cut and seemed too short, I added this offset link and bingo, perfect fit. It's like adding half a link. I have run the chain with the offset link for months now with no chain issues whatsoever. Glad to find these and happy with how they function.

Can come in VERY handy!
I was making three chains for a Tru-Cut reel mower, from one length of 10ft #40 chain. I bought regular connectors pins, then saw these afterward and thought "just in case" and picked up a pack to have on hand on the off-chance I'd need them. And boy was I glad I did! Turned out TWO of the factory chains I removed from the mower were made with a half link, so I never would have gotten the right length without having these! They also use an easy little cotter pin to lock them on, instead of the snap-on pins the full-length connector pins use which are a PITA. Highly recommended.
