Kits include Rails, Tapped Strips, Filler Ears, Side Panel Spacers and hardware.
Slim Racks are only available as a 3U configuration.
NB the Filler Ears add just under 4HP to the total Slim Rack width so if your cabinet opening is, for example, 92HP (467mm) then you should specify (92 - 4 =) 88HP as the desired rail length.
Upgrades to M2.5mm Tapped Strips are available - please add 'Upgrade to M2.5mm' in the Comments section at the checkout.
