RSF1120K3V2 Low Profile Adjustable Rails Kit

Adjustable Rail


The RSF1120K3V2 4 Post low profile adjustable rails provides a simple, low cost solution for managing your Desktops, Mini-Towers and non-rackmountable equipment in a standard 19”, 23” or 24” EIA rack. Traditional rack shelf occupied at least 1U of rack space for use on any type of Desktop PC, Mini-Towers and non-rackmountable equipment. If you wish to reduce the rack space size, your equipment must have mounting holes on both side to support a pair of 19” or 23” rack ear (L bracket). If your non-rackmountable equipment or computer system do not have the right mounting holes or rack ear support, RSF1120K3V2 might be the solution for you. RSF1120K3V2 is design specially for mounting desktop computer, mini tower computer and non-rackmountable equipment in a standard rack. Its low profile design occupied less than 1U of rack space. It functions just like a standard rack shelf except it uses minimum amount of rack space.

The new and improved RSF1120K3V2 offer several new features over our standard RSF1120K1 rail.

Universal Rack Support

RSF1120K3V2 is design to support various depth 4 post rack cabinet from 16” up to 38” in depth. Our unique S body rail design and heavier 14 gauge thick sheet metal ensures proper weight support in any depth adjustment.

Anti-sliding feature

Most of the fixed or adjustable rail or shelves have open end at front and back. There is nothing to stop your equipment from sliding off the rail or shelves. Our RSF1120K3V2 offers anti-sliding bracket and hook holes for bungee cords to reduce sliding issue. You can install our anti-sliding bracket on front and back of our rail bracket to keep your equipment secure in place. You can also use bungee cord to further restricting movement in the rack.

Horizontal Adjustment bracket

You can reduce horizontal movement with our horizontal adjustment bracket for your equipment, mini Desktop and Tower Case. You can adjust the bracket to match width of your equipment.

RSF1120K3V2 is ideal for 1U, 2U, 3U or 4U lightweight network equipment, telecom equipment, computer servers, and workstations installation. No drilling into your equipment needed. You simply slid your equipment in and done. In short, RSF1120K3V2 offers rack mounting support at an affordable price.
