Perfect match for the Longer B1
Works well with the Longer B1 (the 50mm set). No instructions, but not too difficult to figure out. They screw into the machine, the idea is to screw the originals into the bottom of the extentions. The bolts are not set into the extension and are rather loose in shipping. Some were found in the box, but some, instead of working loose and falling out, rotated in the opposite direction and worked their way into the extension...out of reach without an xacto knife to screw them out. Loctite or super glue is your friend here, if you plan on removing then occasionally. Only on the extension end though. They match the color of the B1 perfectly. You get 100mm of rise with both sets screwed together.
