19 in rail
Nominal panel width is 19 in. Usable opening is narrower and must come from the drawing. Hole choice is square, tapped 12-24, or mixed. Spacing repeats 0.625 in, 0.625 in, 0.500 in. Cage nuts are an accessory line if the holes are square.
Quotation scope · wall server cabinet
12u wall mount server rack
Factories quoting a 12u wall mount server rack need one shared question list. LinkScope Sourcing 46 collects that list as an independent sourcing partner and sends it onward. The service is coordination of answers, not a warehouse release and not an engineering stamp.
Rail height for twelve units is 21.00 inches, which is 533.4 millimeters, using the 1.75 inch unit from EIA-310. Write that as the opening the equipment occupies. Then write a second number for the outer skin, because cartons, top knockouts, and the hinge barrel sit outside the rails.
The 27 October 2026 measured file lists US volume 40 for the phrase 12u wall mount server rack. Volume is not a promise of factory capacity. It only marks why this page keeps the phrase tied to quotation fields rather than to a catalog price.
Interfaces the quote must separate
Hinge hand
State left or right as viewed from the room, plus swing in degrees. A 90 degree swing and a 110 degree swing need different floor clearance. If the body is fixed and only a door moves, say so; that is a different steel assembly.
RJ45 panel
If the same RFQ carries a patch panel, name port count, category, and T568A or T568B. Insertion loss, return loss, and 100 ohm impedance stay on the jack sheet. Connector mating cycle is a jack rating, often requested as a cycle count on that sheet, not as a cabinet feature.
Power shelf
A PDU inside the cabinet needs input voltage, outlet or branch count, and whether monitoring is included. Runtime and efficiency apply when a UPS is also in scope. Power over Ethernet is a switch budget and does not belong on the steel price.
Cooling is a fifth interface even without a card: fan count, airflow direction, and the noise or wattage the drawing lists. A passive body and a body with a fan tray are different quotations. Wavelength, optical budget, and dispersion appear only if fiber jumpers are a separate line; they do not describe the cabinet metal.
Condition and jack origin, written as opposing notes
Refurbished frames can be the practical path when a closet already uses an older hole pattern and the seller documents dents, missing latches, and remaining warranty in writing. New frames can be the practical path when you need a current revision, a stated static-load method, and a warranty issued for that model. This desk does not rank one condition above the other and does not hold either.
Compatible keystone jacks can widen supply when plating, category, and the mating-cycle figure are checked against the panel cutout. OEM-coded jacks can align more directly with a vendor support note when that note is actually in the quote. A photograph of an RJ45 face is not the check.
Three limits sit on every service file. The desk does not certify wall anchors. It does not treat a 60 kg brochure figure as your installed load. It does not fold freight, duties, fans, or a shelf into a silent total. Incoming inspection is a buyer step: count units, check hinge hand, and match the drawing revision before the carton is accepted.
A sample intake from a hallway IDF, marked as a scenario rather than a closed project: twelve rack units, outer depth 18 in, right-hand hinge, plywood backer of 19 mm, quantity of four cabinets to one US dock, panel kept as its own 24-port line. The result of that intake is four factory replies on identical cells, which the buyer then accepts or rejects.
Questions each supplier quotes against
-
Which costs stay outside the cabinet unit price?
Packing, freight, duties, fans, shelf, vertical manager, and the RJ45 panel unless the line item names them. Currency and Incoterm belong in the commercial block. A per-cabinet budget and a whole-order budget are different ceilings; label the one you mean.
-
What evidence is tied to the model, not the family?
Current datasheet, hole drawing, load-test basis, and any applicable safety file for that model. ISO 9001, if offered, is a quality-system document for the supplier, not a test of your cabinet. FCC equipment authorization is relevant for active electronics, not for an empty steel box. NRTL marks, when claimed, need the exact model on the file.
-
How should an alternative be marked?
The supplier splits compliant lines, deviations, and options. A deeper body, a reversed hinge, or a tapped rail instead of square holes is a deviation. Host compatibility of any switch placed inside is unproven until that switch and this rail depth are checked together. Data rate of the copper channel is a cabling question, not a cabinet question.

Send the field list for factory quotations
Include quantity, destination, and the delivery window in the requirement box. Optional budget needs a currency and a per-cabinet or whole-order basis. Supplier preference, if you add one, is high-end, mid-range, budget, or undecided, and it is not a verified rating.
