Shelf closet towers installed in a finished walk-in closet

Glossary

Every closet term we use, defined once.

36 terms defined in one sentence each, with the measurement attached: hanging bays 24 inches deep, shelves 15, towers 84 inches high, holes on a 32 mm grid, and cabinet run priced at $200-$600 per linear foot installed.

Closet quotes are full of words that sound interchangeable and are not. A tower is not a bay. A linear foot is not a square foot. Depth is not a preference; it is set by the width of a shoulder on a hanger.

Every definition below is the same one used on the page it comes from, with the measurement attached. Nothing here is a new claim — it is the site's own vocabulary, collected so a single term can be looked up without reading a product page end to end.

Cabinet and structure

Parts of a closet run.

What the pieces are called and what fixes their size.

Parts of a closet run.
Closet towerA vertical cabinet of adjustable shelves that forms the structural backbone of a closet run; ClosetX towers are 84 inches high and come in five widths from 18 to 36 inches, in 15- and 24-inch depths.
Hanging bayA section of a closet given over to a rod rather than shelves; it is 24 inches deep because a shirt on a hanger measures about 22 inches across the shoulders.
Double hangTwo rods stacked in one bay, at roughly 40 and 82 inches above the floor, which doubles the rod length available in the same wall width.
Long hangA bay with a single rod at about 66 inches, sized for coats, dresses and garment bags that need roughly a 60-inch drop.
Reach-in closetA closet used from outside the opening, typically 15 to 24 inches deep, where the door line fixes the depth and the opening width fixes the layout.
Walk-in closetA closet you stand inside, generally above about 7 feet of clear width; below that a reach-in run along one wall holds more than a walk-in layout does.
Closet islandA freestanding drawer unit in the middle of a walk-in closet; the ClosetX island is 60 inches long, 24 inches deep and 42 inches high with drawer access from both faces.
Ceiling cabinetA 12-inch-high top box that closes the gap between an 84-inch tower and a 96-inch ceiling, converting dead air into closed seasonal storage.
Corner closet unitA cabinet designed to turn the blind corner where two closet runs meet into usable hanging and shelf space instead of an unreachable void.
Drawer base cabinetA pre-built drawer stack that sits under a hanging bay and gives the run a continuous base line, rather than drawers added inside a tower afterwards.
Shoe rackAn angled shelf with a front lip so shoes face outward; at 15 inches deep it takes a men's size 13 and stacks about six rows in an 84-inch tower.
Partition panelA finished vertical panel that divides one bay from the next and carries the shelf and rod loads; it is what makes a run read as cabinetry rather than shelving.

Materials and hardware

What it is made of.

The panel, the edge, the holes and the moving parts.

What it is made of.
Melamine panelAn engineered wood panel with a heat-fused decorative surface; ClosetX uses three-quarter-inch cabinet-grade melamine with matched heat-applied edge banding.
Thermally fused laminate (TFL)The industry name for a melamine panel: a resin-saturated decor layer fused to an engineered-wood core under heat and pressure, which is the construction of every ClosetX cabinet, door and partition panel.
ThermofoilA vinyl film vacuum-pressed over an MDF core, most often seen on shaped and raised-panel door fronts; it is a different construction from the thermally fused melamine used throughout the ClosetX program.
Powder coatA dry finish baked onto metal parts; when the word appears on a closet quote it describes hardware components, not the cabinet panels themselves.
Flat slab doorA door or drawer front made of one continuous panel with no frame joints, which keeps a modern elevation visually quiet and is the easier front to wipe clean.
Shaker profileA door front with a flat center panel inside a plain square-edged frame, offered in the ClosetX program alongside the flat slab for rooms with traditional trim to answer to.
Edge bandingThe finished strip applied to the cut edge of a panel; heat-applied matched banding seals the core and is what separates cabinet-grade work from raw-edged shelving.
32 mm system holesA full-height grid of holes drilled at 32-millimeter centers, which lets every shelf and fitting be repositioned later without tools or new drilling.
Soft closeA damper built into a drawer runner or door hinge that slows the last part of the travel so the part closes quietly and does not rebound.
Full-extension runnerA drawer slide that brings the whole drawer box clear of the cabinet, so the back of the drawer is reachable instead of hidden under the shelf above.
Concealed hingeA door hinge hidden inside the cabinet when the door is shut, adjustable in three axes after installation so door gaps can be trued on site.
Shelf-edge LED lightingA recessed LED strip run into the front edge of a shelf or the underside of a cabinet top, aimed down the face of what is stored rather than at the panel behind it. Offered warm or neutral white and dimmable, with an optional door switch; the edge position is what stops your own shadow falling across the hanging when you open the door.

Measurements

The numbers that decide a layout.

Each one exists because something has to physically clear something else.

The numbers that decide a layout.
Hanging depth (24 in)The 24-inch bay depth used wherever garments hang, set by the roughly 22-inch shoulder width of a hanger plus clearance front and back.
Shelf depth (15 in)The 15-inch bay depth used for folded storage, set by the point beyond which the back of a shelf stops being reachable.
Rod setback (12 in)The distance from the back wall to the rod center line, which is half of a 24-inch hanging bay, so a shoulder clears the back panel and the door alike.
Island walkway (42 in)The clear floor width kept on the sides of a closet island in use, which is what makes a room about 10 feet wide the practical minimum for a 24-inch-deep island.
Passing clearance (36 in)The clear width kept between two facing cabinet runs, below which two people cannot pass and drawers cannot be opened from a standing position.

Pricing

How closet work is quoted.

Two units are in circulation and they are not comparable until you convert.

How closet work is quoted.
Linear foot (pricing unit)One foot of cabinet run measured along the wall, floor to the top of the tower; it is the unit closet work is priced in because material and labour scale with run length, not with room floor area.
Cost per square foot of cabinet faceA price divided by the elevation area of the run (length times height); multiply it by the run height in feet to convert it to a per-linear-foot price, so $50 per square foot equals $350 per linear foot on a 7-foot run.
Fixed price from a dimensioned drawingA quote produced from a measured elevation and component schedule, with installation inside the number, so nothing moves between order and install.

Process

From measure to install.

The steps that turn a room into a dimensioned, priced drawing.

From measure to install.
Field measure (site measure)The on-site visit, typically 45 to 60 minutes, that records the opening, ceiling height, floor fall and every obstruction before anything is drawn. Called a field measure throughout this site; site measure is the same appointment under another name, and a quote written without one is an estimate rather than a price.
ScribingTrimming a panel edge to follow an out-of-true wall or floor so the cabinet meets the building without a visible gap; it is why site measurement precedes cutting.
Elevation drawingA dimensioned front view of the finished run showing every bay, rod, shelf and drawer, which is the document a fixed price is quoted from.
Component programA cataloged set of standard cabinet parts in fixed widths, depths and heights from which a bespoke layout is assembled, as opposed to one-off joinery cut for a single room.

Where each definition comes from

The page behind the number.

Every measurement above is argued somewhere else on this site. Cabinet and hanging terms come from the closet systems pages — in particular the shelf closet tower, the clothes rail closet and the closet island.

The measurement set is collected in the closet dimensions cheat sheet, with rod geometry in rod height and wall distance and walkways in walk-in layout clearances. Depth is argued in 15 vs 24 inches.

Pricing units are set out in cost per square foot vs per linear foot and priced for this market in what a custom closet costs in Atlanta; the planner applies them to a room. Materials are covered in melamine vs wood vs wire and the finishes page, hardware on the accessories page, and the measure-to-install sequence on how it works.

Who builds all this is on the about page, and every page on the site is listed in one place on the site index.
