Modern Rack Rails in Classic Racks?

I then drill a whole through it in a couple of places and bolt it to the rack. It's not as nice as sliders, but it gets the job done for all the systems I've used in the past couple of decades. It wouldn't work well, however, for systems that have big heavy disk drives, for tape drives, etc. It also burns 1 U in the rack. For me that's not been an issue but others have complained about that in the past when I've suggested this. Warner I figure that loosing 1U will be less of a concern than the insulating effects of putting a sheet of wood in there. I?m giving real consideration to jury rigging something. I?ll pick up the rack and then go from there.
