Fixed Ladder Installation Diagram
Because every ladder is trial-fitted in the factory, the install drawing matches what arrives on site. Your crew works from one accurate sheet.
Dimensioned Elevation
Overall height, rung spacing and clear width marked for your standard.
Anchoring Detail
M12 anchor positions, embedment depth and C25 concrete requirement.
Section Marks
Pre-assembly section marks so each crate bolts together in sequence.

Wall-Mounted
Stand-off bracket detail, M12 anchor pattern and levelling notes on one sheet.

With Platform
Platform and walk-thru elevations drawn with the ladder for match-fit.

Cage / PFAS
Cage hoop spacing and PFAS rail bracket rows are dimensioned in the drawing.
Factory-Direct Pricing
Factory-Direct Pricing & 24h Quote
Install drawings free with every order — you only pay for the ladder, at factory price.
Custom quotation priced by weight & process. Industry reference: caged ladders ≈ USD 899–1,099/ton.
Trial-Fit Guarantee
The Drawing Matches the Crate
Our 3,000 m² factory trial-fits every ladder before packing. What you measure in the diagram is what you bolt up on site.
Common questions
A dimensioned front elevation, anchoring details, section marks and the anchor schedule — every fixing position, drill depth and required torque.
Both — sheets are dimensioned in metric and US units, so the crew can work in either system without converting.
Yes — sections are trial-fitted in the factory and marked, so the drawing, the anchor plan and the shipped sections all agree.
C25 concrete minimum; for steel or other substrates we issue an alternative anchor plan with structural calcs before you order.
Every M12 fixing — position, embedment depth, edge distance and torque — checked against your substrate by our engineers.

Fixed Ladder Installation Diagram: Callout Notes, Text Version
Every dimension on the drawing means something on site. Here is the text version of the key callouts — anchors, spacing and clearances — so your crew reads the drawing the same way every time.
M12 anchors per the plan — staggered pairs on each stile. Edge distance ≥60 mm (per anchor datasheet) and embedment depth per the anchor type.
280 mm (11 in), uniform along the run. Rungs are Φ20 mm and 500 mm clear width between stiles.
≥150 mm (6 in) per EN ISO 14122-4; ≥7 in (178 mm) per OSHA 1910.23. Measured from the rung centerline to the wall surface.
200 mm (7.9 in) stand-off for wall-mounted installs — keeps toes behind the rungs and gives the anchor brackets a clean bearing surface.
Φ700 mm (27.6 in) internal diameter. Start height typically 7–8 ft above grade for OSHA-style installations; hoop spacing per your standard, dimensioned on the sheet.
At the interval your standard requires — EN ISO 14122-4: max 6 m between rest platforms. Every platform position is dimensioned on the drawing.
42 in (1,067 mm) of side-rail extension above the landing per OSHA 1910.23, with grab rails where required.
PFAS or ladder safety system above 24 ft (OSHA 1910.28). Each pre-assembled section is numbered to match the drawing for match-fit on site.
Fixed Ladder Installation Diagram: Common Questions
General arrangement, anchoring plan, section drawings and the DoC — metric and US units on the same sheets, so the crew can work in either.
Yes — send your site measurements or photos and our engineers review and dimension the drawing free of charge, before you place the order.
Send the measured values and we re-issue the anchor plan and section lengths, so nothing is cut or re-drilled on site.
