Payment options

This depth adapter kit lets you extend or reduce the mounting depth of two rack units (2U) in your server rack by up to four inches. If you're using the adapter kit in a two post installation the extenders can support a total weight load of 20 lbs. (9 kg). If you're using the adapter kit in a four post installation, the extenders can support a total weight load of 130 lbs. (59 kg), you can even use two sets of extender brackets in a four post installation and achieve the same weight capacity performance.

This TAA compliant product adheres to the requirements of the US Federal Trade Agreements Act (TAA), allowing government GSA Schedule purchases.

Mount equipment that's too long, or too short

You can use this adapter kit to mount equipment in your server rack that's up to four inches longer or shorter than the rack's mounting depth.

Save money by mounting all of your equipment in one rack

With this adapter kit, you can customize your server rack to support different mounting depths, so you have the freedom to mount equipment of different depths in the same rack. It?s a cost-saving, hassle-free way to consolidate your equipment into a single rack, so you have one server rack to manage instead of two.

Easily manage cables by creating additional space

The depth adapter kit can also help manage your cables. You can mount equipment 4? in from the rails, to prevent cables from protruding from the rack. You can use the rail depth adapter to mount equipment that has high density cabling, such as patch panels, PDUs or network switches, to minimize the effects of cable strain and provide easier access to the cables.

The RDA2U is backed by a 2-year warranty and free lifetime technical support.

RoHS compliance The Restriction of Hazardous Substances (RoHS) Directive aims to restrict certain dangerous substances commonly used in electrical and electronic equipment. Any RoHS compliant product is tested for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). PBB and PBDE are flame retardants used in several plastics. For Cadmium and Hexavalent chromium, there must be less than 0.01% of the substance by weight at raw homogeneous materials level. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at raw homogeneous materials. Any RoHS compliant component must have 100 ppm or less of mercury and the mercury must not have been intentionally added to the component. In the EU, some military and medical equipment are exempt from RoHS compliance.
