Koch Industries7540040 Roller Chain Connector Link, 40, Dark Grey

This four pack was less expensive than a single connector link from many other sources. I used this along with a #40 Stainless Steel Roller Chain from General for a driveway gate. The stainless roller chain was also good, but came with only one connector link per 10 foot package of chain. As you can easily confirm by thought experiment or actually trying it, roller chains generally need to be fastened to both ends of the gate to work properly. Otherwise, you run into that "pushing on a chain" problem.The link itself fit properly and was easy to install, once you remove one pin from the stainless roller chain. Note that the pins in stainless chain are also stainless steel, and are harder to get out than on regular steel. An effective way to do this in the field requires a hammer, a punch, and a hex nut. 1. Set the nut on a solid object. 2. Put the chain on top of the nut, with the pin you want to remove over the hole in the nut. 3. Set the punch against the pin to be removed and hit the punch with the hammer. For quality chain, don't expect it do come out very easily, more like 2 minutes if you are fairly precise. 5. You might have a pin which is not all the way out, but can no longer be reached with a punch. Then use pliers to take it out from the other side.

My bad. This link is not the right size for bicycle chain. Make sure it is what you want.

While using my snow blower last winter, I found a couple rocks that I wish I hadn't, and the end result was breaking my snow blower's drive chain. I could have bought a 50 dollar replacement from the dealer, or make one with Koch parts. I chose the latter. I haven't had a problem with my drive chain since, and still have spare parts should the need arise. These roller chain connector links are very easy to use, and very tough. Get some of these! If you have a #40 chain, it's just a matter of time before you will need a new connector!

I had it on a minibike and when I would try to pull off the chain would fall off because the like was too weak and would bend then I would have a hard time trying to get the connector back on the link s

Fits my opener.

As described and works perfectly with the Koch #40 chains I purchased at the same time. In addition I purchased the Koch chain breaker which did the job of splitting one of the chains to add extra length to the other 10 foot chain. Great products for the money, I was quoted much higher prices for the same or very similar products. My very heavy 12 foot gates (x 2) are working well, Oh and very fast shipping !

Sturdy

Great value
