NetApp DS4246 Rails

I've been look everywhere for rails to rack a NetApp DS4246 but cant seem to find any that fit.

If any one could it would be great.

Rails cant be more than 24" inch deep due too shitty rack. Preferably sliding but dont mind. No real price point just any that would fit.

I've tried APC rails and netapp was too wide, and netapp rails that said it would work but they were too deep
