The rails attach to the HL15 with three screw positions on each side. See below for screw positions and spacing;
You’d have to see if your 00057’s have those three screw positions. The HL15 doesn’t use the tool-less rail attachment mechanism found on some Supermicro chassis. For screws, I think everyone gets the screws to attach the rails in the little blue accessories baggie, regardless if they order one of the rail kits. If not, you might have to confirm the screw diameter and thread. You may or may not have chassis attachment screws for your current rails depending on your chassis, how you acquired the rails, if you save “extra” parts, etc.
There could be other fitment factors, but that would be the main one.
I don’t think the 45HL price for the rails is special, so you could order without rails and see if the ones you have do fit. if not, the new or used 00053’s or 00058’s should be readily available in the Supermicro store at Amazon or eBay or back at the 45HL store or other source relatively quickly at no net additional cost.
