Chrome double cantilever arm and mounting bracket

Wall mounted shelving is what a hospital room turns to when the floor is already full. Cantilever arms carry a shelf straight off the wall or off the back posts of an existing unit; hang rails add a row of bins under a shelf; bin rail packages give a complete wall run in one part number. This page covers the published sizes, depths and load figures, and how to specify a run. It sits under wall mounted medical storage.

Cantilever arms and shelves

The arm is the product. The shelf is chosen separately, which is what makes the system flexible and also what people forget to order.

The manufacturer’s current cantilever pages describe the system as a way to create storage space where floor space is not available, and list 40 arm models across single and double arm styles in chrome and in epoxy finishes. Each order is published as including two cantilever arms and two mounting brackets, with the wire shelf sold separately. The live pages list three depths — 14, 18 and 24 inches — while the printed wire literature publishes five, adding 12 and 21 inches. We quote whichever the current price file confirms for your finish.

Complete single-shelf wall-mount packages are also published: a 12-inch deep shelf in lengths from 24 to 72 inches (models WDWB1224 through WDWB1272), which is the simplest way to buy a plain wall shelf run. For shelves hung off the back posts of an existing shelving unit, the manufacturer publishes cantilever shelves with a drop mat design that gives a ledge around the shelf, in 12 by 24 inch up to 12 by 60 inch sizes, in Proform green, grey and black epoxy, with a published load capacity of up to 150 lb per shelf and a note that the unit will need taller rear posts.

Every figure above is the manufacturer’s published figure. Every model number, dimension and finish on this page comes from the manufacturer’s current published literature or a live product page loaded on 5 August 2026, and is quoted as the manufacturer’s own figure. Where a configuration is not published we say so rather than estimating it. What a particular wall will carry is a site question for your facilities team; we do not publish a load figure for anyone’s wall.

Hang rails and bin rail runs

Hang rails mount between shelving posts or on a wall frame and carry a row of hanging bins under a shelf, in space that is otherwise wasted. The manufacturer publishes six lengths — 14, 18, 24, 36, 48 and 60 inches — in chrome, with stainless steel published from 18 inches up.

Bin rail holders do the same job with more adjustment: chrome, published in 24, 30, 36, 48 and 60 inch widths, adjusting in 1-inch increments, with the manufacturer publishing how many of each bin size fits each rail. A 36-inch rail is published as holding 8 of the smallest bins or 6 of the 10-7/8 by 5-1/2 by 5 inch size.

Complete bin runs. If you want the whole thing in one part number, the published wall-mount cantilever bin packages are 34 inches high with three bin rails, in 24, 30, 36, 48 and 60 inch widths, holding 9, 12, 18, 24 or 30 bins with the bins included, in chrome. Bin colours published for those packages are blue, green, ivory, red, yellow, black and clear. The manufacturer also publishes cantilever packages with baskets. For the bins themselves see medical bins and containers, and for a full unit rather than a wall run see bin shelving systems.

Where wall shelving is the right answer

Deep double cantilever arm for wall mounted wire shelvingDeep arms over a work surfaceA deeper arm carries a shelf above a bench without a single leg on the floor, so the counter and the floor both stay cleanable.
Pair of chrome wire shelves on wall mounted cantilever armsTwo or three shelf wall runsStacked arms give a short run of shelves in a corridor alcove, substerile room or clean utility where a floor unit would not fit.

The recurring cases are small rooms that already have their floor committed, benches in sterile processing where nothing may sit on the work surface, operating rooms where the floor has to be clear for cleaning, and new construction where wall blocking can still be added before the walls close. If the volume is genuinely too large for wall runs, high density storage is the honest alternative rather than more shelves.

Specifying a wall run

1Check what is behind the wall firstStud spacing, block, tile, services and existing blocking decide what is possible. This is the step that gets skipped and it is the one that stops installations.
2Choose depth from the item and the roomDeeper arms hold more but eat headroom and elbow room above a bench. Published depths run from 12 to 24 inches.
3Order arms and shelves togetherArms are published as two arms and two brackets; the shelf is a separate line. Half the reorders we see are a missing shelf.
4Decide shelf, rail or bothShelves for cartons and trays, hang rails or bin rails for small items, and often a shelf with a rail underneath it.
5Set heights around the peopleTop shelf readable and reachable by the shortest user, bottom shelf high enough to clean under.

Estimated figures only. Quantities, footprints and capacities we produce during planning are estimates for discussion. Final specifications and dimensions are confirmed on the quote and field-verified before installation.

Wall mounted hospital shelving FAQ

What depths and lengths are published?
Cantilever arms are listed at 14, 18 and 24 inches on the current product pages, with 12 and 21 inches also published in the printed wire literature. Complete wall shelf packages are published 12 inches deep in lengths from 24 to 72 inches, and hang rails in 14, 18, 24, 36, 48 and 60 inch lengths.
How much will a wall shelf hold?
The manufacturer publishes up to 150 lb per shelf for its cantilever shelves with the drop mat ledge. Load figures for other arm and shelf combinations are confirmed per configuration on review. What your wall will carry depends on its construction and fixings, which is a site question for your facilities team — we will not publish a number for it.
Is the shelf included with the arms?
No. Each cantilever order is published as two arms and two mounting brackets, with the wire shelf sold separately. The complete WDWB packages do include the shelf, which is why we usually quote those for plain shelf runs.
Can wall shelves hang off an existing shelving unit?
Yes. The cantilever shelves are designed to attach to a unit’s back posts, and the manufacturer notes that the unit will need taller rear posts to accommodate them. Bin rail holders clamp to posts in the same way.
Can we get bins and shelves on the same wall run?
Yes, and it is usually the best layout: a shelf for cartons and trays with a hang rail or bin rail of small-item bins underneath. Complete bin packages are also published at 34 inches high with three rails and 9 to 30 bins included.
What finishes are available?
Chrome and stainless steel on the rails, and chrome plus Proform green, grey and black epoxy across the cantilever families. Finish availability varies by model, so it is confirmed on the quote.
Do you check the fixings?
We review them with you and with your facilities team, and we ask what is behind the wall before quoting. Fixings are supplied and confirmed on site because stud, block, drywall and tile each need a different answer.
