Brother KR587 ribber is a standard-gauge attachment that converts older knitting machine models to a double bed.

Brother KR587 ribber shares the manual with Brother KR586 ribber. However, the manual mentions that not all accessories are included with KR587. That’s very strange to me, so stay tuned as I am investigating more.

A chart from CreationsGroup states that Brpther KR587 is compatible with KH588 pushbutton machine and with a couple of other machines, but with additional pieces.
