Custom Server Cabinets & Rack Frames
Server cabinets and open racks carry equipment on 19-inch rails behind doors that pass air. K-Display makes server cabinets, network cabinets, open server racks, and rack frames from your drawings.
Server cabinets and rack frames we build
Rack frames are the welded or bolted structures that carry the rails, doors, and panels of a server cabinet or open rack, and we build them with 19-inch rails, or 23-inch rails for telecom relay racks. Frames are made from aluminum, stainless steel, carbon steel, galvanized steel, or galvanneal, with welds in stainless steel, carbon steel, or aluminum, then powder coated with hinges, latches, and casters or leveling feet installed. They ship assembled or knocked down.
The boxes that slide into the rails are built as rack-mount enclosures, and a rack that stores parts or totes as parts racks & shelving.
Air enters through the perforated door and cable runs up the channel beside the rails, both along paths the frame leaves open. Where the door and side panel stand relative to the rails decides how much of that room stays open.
Cabinet and rack parts we make
- Cabinet frames and open racks
- Welded or bolted frames and two-post or four-post open racks in rack-unit heights, with members for rails, doors, and panels.
- Rails
- Front and rear rails cut with square holes for cage nuts or round holes, at fixed or adjustable depth positions.
- Doors and panels
- Perforated, solid, or split doors with hinge side and latch, and side, top, and bottom panels with cable entries, brush strips, or grommets.
- Cable management brackets
- Vertical manager brackets, tie-off bars, and PDU mounting brackets.
What the frame leaves for the equipment
- Welded or bolted
- A welded frame ships as one piece and a bolted frame ships knocked down, which decides whether the cabinet gets through the door, dock, or elevator.
- Rail hole style and datum
- Rack-unit spacing runs from one datum on the rail, and the hole style, square for cage nuts, round, or tapped, sets how equipment fastens.
- Interior clearance
- The space between the rails and the doors and side panels decides whether the deepest equipment, cable bend, managers, and PDUs fit.
- Doors and airflow
- Open area sets airflow and also door stiffness and how much of the interior shows, and a door with too little open area starves the top of the rack of air.
The frame is coated before the doors go on
Powder coat insulates, so door-to-frame contacts, ground studs, and rail bond points are masked before the frame is coated.
Cut the members and rail holes
We cut the frame members, panels, and doors with the rail hole pattern, and form them.
Weld or kit the frame
We weld the frame and blend the welds, or leave it in parts for bolted assembly.
Coat and assemble
We press in clinched nuts, studs, and captive screws, then powder coat the frame, doors, panels, and brackets together. We hang the doors, fit panels and managers, and mount casters or feet.
Set rail depth from the equipment
Show the deepest unit and its rear connections when choosing the rail positions. Cable managers, PDUs and the closed door consume the same interior space, so the frame layout needs to include them before panels are cut.
The rail attaches to slotted depth supports on the frame. Its position sets the room available in front of and behind the equipment, so the upper and lower attachments must hold the rail in the same plane.
What to send for a server cabinet quote
- Cabinet drawing or model
- Welded or bolted construction, member type and thickness, material, height in rack units such as 42U, width, depth, and quantity.
- Rails and clearances
- Rail standard, hole style, rail thickness and finish, deepest equipment, and rear cable and PDU clearance.
- Doors and panels
- Door type and open area, hinge side, latch part number, and panel and cable entry details.
- Accessories, base, and finish
- Cable manager and PDU drawings, caster or foot part numbers, bolt-down details, coating color, and bonding points to keep bare.
