#25 Chain K1 Masterlink

[1629GaCo]

Does anyone know where we can find a K1 or A1 masterlink for #25 Chain? Any help would be greatly appreciated.

I'm not sure if its what you are looking for, but Andymark does have a masterlink for #25 chain (am-0371) (http://www.andymark.com/product-p/am-0371.htm).

McMaster has #25 master links I think.

If so, we too needed these however they were awfully expensive anywhere we looked ($25-$35 for a pack of 5 without shipping). So we were able to actually make them by replacing middle piece in this photo:

with a small bracket I made using a hand drill and file. now all we have to do is buy masterlinks ($1 a piece where we are) and make a piece of sheet metal with a flange to make a $6-$7 part.

In the past, we have taken a normal hex head bolt to the grinder and made something similar to this. (http://www.proteccontrols.com/catalog/product_info.php?currency=USD&products_id=225&gclid=CjwKEAiAoo2mBRD20fvvlojj5jsSJABMSc7jnLcVPs5f iUOYmt0c5mvoFrtd0k12dux2YZ4FZjuh7xoC0ubw_wcB) This also gives the ability to tension your chain without an idler anywhere.

Also, Vex has their new VersaFrame Roller Chain Mount. (http://www.vexrobotics.com/vexpro/versaframe/versaframegussetsandmounts.html) You could bolt through three links with this plate and make your own K1 Masterlink of sorts.

We didn't like the low apparent pull capability of these "links with wings," as the specs indicated we could only get a #4 screw through the #35 version. Instead, we bought some thumbscrews locally. We then drilled holes through the "handle" big enough for one side of the master link to engage, close enough to the edge so we could engage the last small link on the chain. We passed the thread end through a hole in our lift and secured with jam nuts. This also gave us the capability of adjusting chain tension with a wrench. The idea was borrowed from a garage door opener.

What's wrong with just sticking #8 screws through the area between the rollers in the chain?

Could be the orientation of the piece they want to mount it to. For instance, the wings on the linked picture above are for mounting something directly behind the holes. If you rotate the chain 90 degrees (ie. screws through the holes in the chain would be parallel to the face you are trying to mount on) then they wouldn't work right out of the box. A COTS solution for this would be nice, but it can be solved easily without one. My team is bending a T Gusset 90 degrees in order to put screws through chain and then mount to a parallel surface.

A local hardware store. We get ours from ACE hardware.

The VersaFrame Roller Chain Mount will work I think, thanks for the replies.
