# Custom Server Cabinets & Rack Frames

https://kdisplay.com/products/chassis-cabinets/server-cabinets-rack-frames

K-Display, a Chicago sheet metal fabricator, builds server cabinets, network cabinets, open racks, and rack frames from customer drawings: 19-inch or 23-inch rails, perforated or solid doors, side panels, and cable manager brackets. They ship welded or knocked down and powder coated, with casters or feet fitted.

## Overview
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 &…

## Process
- 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.

## Typical parts
- 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.

## Design considerations
- 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.
