We are unfortunately not able confirm compatibility for the XB-2 since the 002-159-KS100 is designed for use with SK and XK series models. The XB-2 is approximately 45.8 x 12.24 x 3.97″ and weighs about 30 lbs. It seems to be fairly close in size to the SK1-73 which is 44.3 x 11.9 x 3.9" but lighter at 20.5 lbs like many of the SK and XK models. The SK1-73 is compatible with the Hammond 002-159-KS100 so the stand might also work for the XB-2. Since the Hammond 002-159-KS100 is only available by special order, you may want to consider a similar stand that is available in stock. We recommend the On-Stage KS7150 Platform-Style Keyboard Stand (B&H # ONKS7150) which supports up to 230 lbs and has an adjustable width of 29 to 43.5", a depth of 12", and is height adjustable from 26 to 43". The KS7150 is strong and stable, highly rated, and also close in price to the Hammond stand so it would be a very good option to consider.
