One manufacturer, two genuinely different approaches: a rail rated for weight, and shelves that expand so you never have to cut.

Rubbermaid sells two different ideas: FastTrack is a rail system rated at 1,750 lb for the rail, and Configurations is a kit with telescoping shelves that expand to fit an odd width without cutting. Choose FastTrack for weight and future reconfiguration; choose Configurations if your closet width does not match a stock kit and you would rather not own a hacksaw.
Both depend on studs, and Rubbermaid is unusually direct about it. Its installation guide states that maximum rated capacity is not achievable at 24 inch stud spacing — a sentence no competitor puts in writing, and the most useful thing on this page.

What it gets right
The published rail rating is the highest figure any of these manufacturers puts in writing
Components unhook and move without touching the wall again
The same rail carries closet shelving and garage hooks, so parts are interchangeable
What it does not
The rail is visible and industrial-looking in a bedroom closet
Its whole rating is contingent on stud count, which you cannot change
Who it is for
A closet carrying real weight — a coat closet, a utility closet, or a walk-in that doubles as overflow storage.
Skip this if
You have a 48 in opening with only two studs behind it. Rubbermaid asks for four on that length, and the rating is meaningless without them.

Fitting an odd width without cutting
Rubbermaid Configurations Custom Closet Kit
Telescoping shelves that expand to fill a range of closet widths, so an awkward opening does not force you to cut metal.
Telescoping shelves expand across a width range rather than one fixed size
Mounts to
A single hang rail spanning the closet, screwed into studs
What the rating depends on
Rubbermaid's rail guidance is that the rail begins and ends on a stud, with anchors every 8 in between. At 24 in stud spacing the maximum rated capacity is not achievable.Source: Rubbermaid FastTrack Rail and Shelving Installation Guide
Per-kit published load
Not published by the manufacturer in a form we could verify for the Configurations kits specifically.
What it gets right
Expanding shelves absorb a width that does not match a standard kit
One rail carries the whole system, so there is one line to level rather than several
Comes as a kit — rod, shelves and hardware in one box
What it does not
A telescoping shelf is two overlapping pieces, which is less rigid than one solid run
The rail concentrates everything on one line of fixings; a bad rail install compromises the lot
Who it is for
Someone with a non-standard opening who would rather set a width dial than take a hacksaw to a shelf.
Skip this if
Your studs are on 24 in centers. Rubbermaid's own guidance is that maximum rated capacity is not achievable at that spacing, and a closet full of winter coats is exactly where that matters.

24 in apart, and no more than 4 in from the end of the shelfSource: ClosetMaid ShelfTrack Installation Tips
Published load
About 83 lb per bracket, up to 1,000 lb across a full systemSource: ClosetMaid Wire Shelving Specifications, rev 6/12
What the rating depends on
At least 3 screws into studs in the hang track and 3 in the middle standards. Fewer than that and the published figure does not apply.Source: ClosetMaid ShelfTrack Installation Tips
Adjustable after install
Yes — shelves move on the standards without re-drilling
What it gets right
Shelf heights change later without new holes in the wall
The hang track spreads load across studs rather than into single anchors
Widely stocked, so a replacement bracket is easy to find years from now
What it does not
The visible track and standards are not a design feature; some people hate the look
Rated capacity is entirely dependent on hitting studs, which older homes make harder
Who it is for
Anyone with a standard 24-inch-deep reach-in who expects the contents to change — a growing child's closet, a first apartment, a closet you are not sure about yet.
Skip this if
Your closet wall is masonry or plaster over brick. The published load figures assume wood studs, and anchor-only installs do not reach them.
The 1,750 lb figure, in context
It is the highest published number in this whole category and it needs reading carefully. It describes the rail, not the closet. What the rail carries is transmitted into the studs it is fixed to, and Rubbermaid's requirement of four studs for a 48 inch rail and six for an 84 inch rail is the real constraint.
Do that arithmetic on your own wall before buying. A 48 inch rail needs four studs, which on 16 inch centers means the rail spans exactly the right run — and on 24 inch centers you get three at best. Rubbermaid tells you what that costs you, which is the point of the sentence about maximum capacity.
Configurations and the telescoping trade
A telescoping shelf is two overlapping pieces that slide against each other. That is what lets one kit fit a range of widths, and it is also why it is less rigid than a single cut shelf of the same nominal length. For clothing it is fine. For anything dense on a long span it is a real difference.
The alternative is buying a fixed system and cutting the shelf, which is not difficult — see cutting wire shelving — but does require a bolt cutter, a hacksaw and a file. Configurations exists so that you do not need any of them.
Rubbermaid against the others
Against ClosetMaid: Rubbermaid publishes a higher rail figure and a stricter condition; ClosetMaid publishes better spacing documentation and costs less. Full comparison on ClosetMaid vs Rubbermaid vs Elfa.
Against Elfa: Rubbermaid is cheaper and widely stocked; Elfa is better finished and more forgiving about studs.
Against a freestanding rack: if your studs are on 24 inch centers and the load is heavy, a freestanding NSF rack publishes up to 800 lb per shelf with no stud condition at all. See shelf span and weight.
FAQ
Questions people ask about this
How much weight does a Rubbermaid FastTrack rail hold?
Rubbermaid publishes 1,750 lb for the hang rail. That figure assumes the rail begins and ends on a stud, with a 48 inch rail hitting four studs and an 84 inch rail hitting six, and anchors every 8 inches between studs.
What is the difference between Rubbermaid FastTrack and Configurations?
FastTrack is a rail system built for weight, with components that hook on and off without tools. Configurations is a kit whose shelves telescope to fit a range of closet widths, so an odd opening does not require cutting.
Does Rubbermaid closet shelving need studs?
Yes, and Rubbermaid is explicit about it. The rail must begin and end on a stud, a 48 inch rail must hit four studs, an 84 inch rail six, and maximum rated capacity is not achievable at 24 inch stud spacing.
Are telescoping closet shelves strong enough?
For clothing, yes. A telescoping shelf is two overlapping pieces sliding against each other, which is inherently less rigid than a single cut shelf over the same span. For dense loads over a long run, cut a fixed shelf instead.
Can Rubbermaid FastTrack be used in a garage and a closet?
Yes — the rail profile is shared, so closet and garage components hook onto the same rail. That interchangeability is unique among the systems we compared.
