The Complete Guide to Cabinet Industry Terminology Every Buyer Should Understand
Cabinet terminology falls into a few groups: cabinet types (base, wall, tall), materials (plywood, MDF, particleboard, veneer), construction (face frame, frameless, overlay, dovetail), finishes and hardware, measurements, catalog codes such as B15 or W3030, and installation and ordering terms. This glossary defines each in plain language so quotes, catalogs and supplier conversations make sense.
Key takeaways
- Most cabinet codes combine a type letter with width and, for wall cabinets, height in inches: B15, SB36, W3030.
- Box material, drawer joinery and hinge type say more about quality than the door style does.
- Overlay (full, half, inset) describes how the door sits on the cabinet and determines the hinges.
- Codes and spec wording vary by manufacturer; always read the specific catalog before ordering.

| Veneer | Thin slice of real wood glued over a core panel for the look of solid wood. |
| Laminate / thermofoil | Synthetic surface layers applied over MDF or particleboard. |
| Species | The type of wood: birch, maple, oak, cherry and so on. |

| Half (partial) overlay | Door covers part of the frame, leaving more frame visible. |
| Inset | Door sits inside the frame opening, flush with the face. |
| Dovetail joint | Interlocking joint used at drawer box corners; strong and resists pulling apart. |

4. Finishing and Hardware
| Term | Meaning |
|---|---|

Reading a Cabinet Spec Sheet: A Worked Example
Here is how the CCC Cabinets catalog specification translates into the terms above:
- “Full overlay, recessed square door profile”: shaker-style doors that cover most of the face frame.
- “3/4″ birch face frame”: a solid hardwood frame on the front of each box.
- “1/2″ A-grade plywood with wood veneer” sides: a plywood box, top-grade face, with a wood veneer surface.
- “1/2″ full plywood back”: a full plywood back panel rather than a thin hardboard back.
- “3/4″ A-grade plywood adjustable shelves”: thick shelves that resist sagging, set on adjustable supports.
- “17 mm solid wood dovetail drawer box”: drawer sides of solid wood joined with dovetails.
- “1-1/4″ concealed 6-way adjustable soft-close hinges”: hidden hinges that close softly and adjust in three directions.
- “MDF door center panel”: the recessed panel is MDF, which stays flat under paint.
The same specification applies to all 15 styles in the kitchen cabinets in Chicago collection, from Pure White to Millennium Grey.
8. Frequently Asked Questions
What does B15 mean on a cabinet order?
B15 typically means a base cabinet 15 inches wide. Most catalogs combine a type code with the width, and for wall cabinets the width followed by the height, so W3030 is a wall cabinet 30 inches wide and 30 inches high. Codes vary by manufacturer, so check the supplier’s catalog.
What is the difference between framed and frameless cabinets?
Framed cabinets have a solid wood face frame on the front of the box that the doors attach to. Frameless cabinets have no face frame; doors mount directly to the box sides, giving slightly wider openings and a flatter modern look. Each uses different hinges.
What does full overlay mean?
Full overlay means the doors and drawer fronts cover almost the entire face frame, leaving only small gaps between them. It gives a clean, continuous look. Half overlay leaves more frame visible, and inset doors sit inside the frame flush with the face.
What is a filler in kitchen cabinets?
A filler is a strip, usually finished to match the cabinets, used to close gaps between a cabinet and a wall, appliance or corner. Fillers let standard-width cabinets fit an exact wall length and give doors and drawers room to open past handles and trim.
What does RTA mean for cabinets?
RTA stands for ready-to-assemble. The cabinets ship flat in boxes and are assembled before installation. RTA reduces freight volume and is often available sooner, while pre-assembled cabinets arrive built and save time on site.
What are the benefits of plywood box cabinets?
Plywood boxes are strong and stable, hold screws well and resist sagging and moisture better than particleboard. That makes them a good choice for sink bases, heavy dish storage and rental units that see hard use.
How should I clean and maintain kitchen cabinets?
Wipe with a soft cloth, mild detergent and warm water, then dry. Avoid harsh chemicals and silicone or wax products, which can damage finishes. Wipe up spills promptly, fix leaks under sinks quickly, and adjust hinges if doors shift with the seasons.
