Cage Ladder Compliance Requirements
Cage Ladder Requirements – EN ISO & Code Guide
The core cage ladder requirements live in the geometry — rung size, spacing, clear width and the safety cage itself. We build every ladder to EN ISO 14122-4 and document the code compliance guide with the order.
- EN ISO 14122-4 geometry
Rung Φ20 mm @ 280 mm spacing, 500 mm clear width, cage start 2.2 m
- Code compliance guide
OSHA, ANSI and EN ISO rules mapped to one checklist
- DoC & conformity statement

Multi-Standard Overview
Cage Ladder Code – Multi-Standard Overview
One ladder, several codes. The comparison below maps the cage ladder requirements across the standards most facilities need to satisfy.
| Requirement | OSHA 1910.28 | ANSI A14.3 | EN ISO 14122-4 |
|---|---|---|---|
| Fall protection trigger | Ladders over 24 ft (7.3 m) | Ladders over 24 ft (7.3 m) | Safety cage from 3.0 m (ours from 2.2 m) |
| Cage / guard role | Required where personal fall arrest is not used | Required above 24 ft in classic fixed ladder layouts | Guards against falls for ladders > 3 m |
| Rung spacing guidance | 10–14 in (254–356 mm) | 10–14 in (254–356 mm) | 225–300 mm |

Standards Translated Into Buying Language
The Five Elements Every Cage Ladder RFQ Must State
An inquiry that says "cage ladder, 8 m, quote" gets a generic answer, because every standard family would build it differently. An inquiry that states five elements gets a compliance-specific quote in 24 hours — because the five elements are exactly what the standards ask the fabricator to know. This is the same form our engineers fill before pricing.
| Element | State It Like This | Why the Standard Cares |
|---|---|---|
| 1 — governing standard, named | "EN ISO 14122-4:2016" or "OSHA 1910.23/1910.28" or "AS 1657:2018" or "BS 4211:2005+A1" | cage trigger, geometry bands and documentation all change with the standard — the DoC is written against this name |
| 2 — climb height and install date | "9.5 m climb" plus, for US sites, "existing, installed before 19 Nov 2018" | height picks the regime; the date decides whether a cage satisfies or an LSS/PFAS is needed over 24 ft |
| 3 — geometry you require | "rung Φ20 at 280 mm, width 500 mm, cage from 2.2 m, hoops at 1500 mm" | these are the numbers an inspector tapes — stating them fixes them on the drawing and in the calcs |
| 4 — environment and material | "coastal outdoor — SS304" or "industrial inland — Q235B HDG to ISO 1461" | the corrosion budget decides whether the asset survives its inspection cycles |
| 5 — documentation scope | "DoC to the named standard, MTC 3.1, structural calcs, trial-assembly photos" | the compliance file is what your auditor audits — order it explicitly so nothing ships without it |
Copy the five rows into your next inquiry — any supplier who cannot answer all five in writing has told you something too.

New Build vs Existing Asset — the Path Table
New and existing ladders answer to different halves of the same rulebooks. The left column is your reality; the right column is what the purchase order should contain.
| Your Situation | The Rule That Decides | Our Supply |
|---|---|---|
| New build, US site, over 24 ft | installed after 19 Nov 2018 — LSS or PFAS required; a cage alone does not satisfy | rail-compatible ladder build with LSS integrator scope named in the quote |
| New build, EN or AS site | cage from 3.0 m of climb; flights capped at 6 m under EN ISO | caged multi-flight package with platforms at the breaks |
| Existing caged ladder, US, pre-2018 install | cage recognized until 18 Nov 2036 — a September 2025 proposal to rescind the phase-out is not yet final | cage replacement modules, like-for-like, grandfathering preserved |
| Existing sound ladder, cage missing | the geometry survives; only the cage is the gap | retrofit cage to measured stringer geometry, hoops 40×5 at 1500 mm |
| Existing ladder at end of corrosion life | repair spend past a threshold is sunk cost — replace once | new unit at $95 per metre HDG level, full compliance file included |
| Mixed portfolio across jurisdictions | each asset answers to its own standard and its own dates | one inventory sheet, one quote set, DoC per ladder to its own standard |
New, retrofit or replace — send the heights and dates, and each ladder comes back priced on its correct path inside 24 hours.
Feature — Advantage — Your Outcome
Features That Turn Requirements Into Passed Inspections
Five build features, each answering a requirements check somewhere in the world.
| Feature | Advantage | Your Outcome |
|---|---|---|
| One geometry inside every band | Φ20 rung at 280 mm, 500 mm width, Φ700 cage | same ladder passes US, EN, BS and AS tape checks |
| DoC to the client-named standard | the document names exactly what your spec named | no gap between tender language and delivered proof |
| Five-stage QC evidence chain | MTC, welds, coating, trial assembly, photos — 10 years | every audit question has a dated artifact |
| 24 h engineer quote, MOQ 1 | requirements answered by an engineer, not a catalogue | single-ladder projects priced with the same rigor as site-wide |
| Rail-compatible stringer option | future system retrofit without ladder replacement | requirements that tighten later cost a rail, not a rebuild |

Deep Dive — EN ISO Meets BS 4211
Dimension Crosswalk: EN ISO 14122-4 vs BS 4211
Two documents dominate English-language cage ladder specifications: EN ISO 14122-4:2016 across the EU machinery world, and BS 4211:2005+A1:2008 wherever UK specifications and Commonwealth tenders hold sway. They agree more than they differ — and the overlap zone is exactly where a factory builds.
On rungs, EN ISO permits 225–300 mm spacing while BS 4211 works a 250–300 mm band and rates rungs at 1.5 kN; a 280 mm build sits comfortably inside both. On hoops, both cap vertical spacing at 1500 mm. The differences sharpen on the basket: EN ISO defines a 400–600 mm climbing width, while BS 4211 describes a wider 0.6–0.8 m cage basket, and EN ISO adds a 22 mm minimum for single-bar rungs.
Read the crosswalk below before your next tender response — it tells you which dimensions are safe to fix and which must follow the named standard.
| Requirement | EN ISO 14122-4:2016 | BS 4211:2005+A1:2008 | Our Standard Build |
|---|---|---|---|
| Rung spacing | 225–300 mm | 250–300 mm | 280 mm — inside both bands |
| Rung sizing and load | Single-bar rungs 22 mm min | 1.5 kN rung loading | One geometry inside the OSHA/BS bands; EN single-bar builds up-size to Φ22 on request |
| Climbing width / basket | 400–600 mm between rails | 0.6–0.8 m cage basket | 500 mm clear width, Φ700 cage |
| Hoop spacing | ≤ 1500 mm | ≤ 1500 mm | Hoops 40×5 at 1500 mm centres |
| Cage trigger height | Over 3 m climb | Geometry standard — trigger set by the site spec | Cage starting 2.2 m above floor |
| Ladder safety system | Required above 10 m | Not the mechanism — fall arrest per risk | Built LSS-ready on request |
| Documentation route | DoC file under the machinery framework | Conformity statement to the named spec | DoC naming your designated standard |
Fix the Overlap First
Rung spacing, hoop spacing and load ratings are the shared backbone — lock them once and the ladder already stands in both systems.
Then Follow the Name
Basket width and rung diameter are where the documents diverge — we set them to whichever standard your tender names, and print that on the DoC.
One Drawing Set
Dual-market fleets get one GA drawing with two dimension columns, cutting review time for engineering teams on both sides.
