Exterior Roof Access Ladder Drawings and CAD Files
Alaco provides free CAD drawings and specification documents for all exterior roof access ladder models. Each model includes ladder drawings in PDF, DXF, and DWG formats, plus 3-part specifications, bracket details, and security door drawings — everything architects, engineers, and specifiers need for project planning and submittals.
Choose your ladder model below to download the files you need. If your project requires a custom configuration, our team can prepare shop drawings built to your exact specifications.
561 – Handrails over Roof
Fixed roof access ladder with handrails extending above the roof edge for a secure walk-through exit onto the roof.
564 – Parapet Return with Crossover Platform
Parapet access ladder with a crossover platform, allowing workers to safely step over the parapet wall and down to the roof.

People Also Ask
What file formats are Alaco ladder drawings available in?
Alaco provides ladder drawings in PDF, DXF, and DWG formats, as well as specification documents in DOC and PDF formats. DWG and DXF files work with AutoCAD and most CAD software, making them easy to drop directly into your project drawings.
What is the difference between a roof return and a parapet return ladder?
A roof return ladder (model 562) exits directly onto the roof surface, with rails curving back onto the roof. A parapet return ladder (models 563 and 564) is designed to climb over a parapet wall, with the 564 adding a crossover platform for stepping over taller parapets.
What are 3-part specifications?
3-part specifications are formatted specification documents (General, Products, Execution) used in architectural submittals and construction documents. Alaco provides 3-part specs for all heavy-duty exterior ladder models to simplify the specification process.
Can Alaco modify these standard ladder designs?
Yes. Every Alaco ladder can be built to custom heights, widths, and configurations. Our team prepares project-specific shop drawings so your ladder fits your exact structure and meets OSHA and ANSI requirements.
Are these exterior ladders OSHA compliant?
Yes. Alaco exterior roof access ladders are built to meet or exceed OSHA and ANSI standards, including load capacity and rail extension requirements. See our OSHA standards page for full compliance details.
