This Attachment has been designed for the New Generation of ATX® Benches and will not work properly with the older gen.

The main change between the benches were the location of the adjustment pin. It was moved from the back of the front support upright, to the very front.

The height of the pin has also been changed, that is why you will not be able to lock the attachment in properly. 

In saying that, you can slot the attachment in, but instead of being locked it, it will rest onto the previous gen locking pin.
