ZIP ladders are certified according to EN 14975 – the standard for retractable ladders and ceiling hatches.

This standard ensures compliance with requirements for functionality, safety, and load capacity.

ZIP ladders are available in four models depending on ceiling height. The number of steps varies by model and height.

Add 50 mm to the minimum opening width to account for the frame thickness of the CAD-C ceiling hatch.

It is the customer’s responsibility to ensure that the opening size meets their requirements.

Standard Dimensions:

• Minimum opening: 600×900 mm
• Step width: 350 mm
• Step depth: 140 mm
• Folded height: approx. 640 mm

Always read the installation instructions included with your order carefully before beginning any work, as they may vary depending on design and optional features. For proper function and safe installation, assembly should be carried out by a qualified installer. Fixings and mounting points should be adapted to the substrate.

The ZIP ladder is delivered pre-mounted on an 18 mm installation board. This board serves as the anchor point to the ceiling structure or hatch.

During installation, a clearance of approximately 80 mm behind the mounting board is recommended to provide enough space for the ladder mechanism and ensure proper operation when opening and closing. This clearance is not included in the delivery.

The ladder is adjusted and locked in the correct position after installation. Due to the spring mechanism, installation should be carried out with caution.

Always follow the specific operating and maintenance instructions provided with your order. Instructions may vary between different models, materials, and optional features. The ZIP ladder normally requires minimal maintenance but should be inspected regularly.

Recommended Inspections:

• Check the spring mechanism for proper operation.
• Inspect all fixings and bolts.
• Check the steps and scissor mechanism.
• Lubricate moving parts as needed.

Regular inspections help ensure safe use and long service life.

What is a foldable ladder?
A foldable ladder (retractable attic ladder) is installed in a ceiling or opening and can be folded down when access to attics or technical spaces is required. ZIP ladders provide safe, space-saving access in buildings where permanent stairs are not practical.

When should I use a foldable ladder?
Foldable ladders are ideal for attics, under-ceiling installations, ventilation rooms, technical spaces, and other hard-to-reach areas in commercial and industrial buildings.

How much weight can a ZIP ladder support?

• Maximum load per step: 200 kg
• Total load capacity: 500 kg/m²

What ceiling heights do ZIP ladders fit?
ZIP ladders come in four models:

• ZIP 4: up to 2500 mm
• ZIP 5: 2501–2790 mm
