Narrow Access Walkways
Narrow access walkways provide safe, guarded single-file access along the tight spaces where a standard-width walkway will not fit — between closely spaced equipment, along building walls, through confined utility chases, and around obstructions. Some access routes simply do not have the width for a full walkway, yet still need a stable, code-referenced surface and fall protection. A narrow access walkway threads through the available space at reduced width, engineered to provide secure footing and guarding while fitting the tight envelope. Modular Solutions builds each narrow walkway from T-slot aluminum, routing it through the constrained space with grated or serrated decking, 42-inch guarding, and integrated access, holding the clearances the tight route demands. Because the structure bolts together, it installs in confined areas and reconfigures as the layout changes. Narrow walkways connect to standard walkways, platforms, and catwalks to complete an access route where space tightens. For facilities that need safe access through spaces too tight for a standard walkway, narrow access walkways deliver guarded, code-referenced passage engineered to fit.
What Are Narrow Access Walkways?
A narrow access walkway is a reduced-width guarded walkway engineered for safe single-file access along tight spaces — between closely spaced equipment, along walls, through confined chases, and around obstructions — where a standard-width walkway will not fit. It provides a stable, code-referenced surface and fall protection in a constrained envelope.

Key Features
Engineered around your route, clearances, and facility — not a catalog template.
Fits Tight Spaces
Reduced-width walkway threads through confined routes where a standard walkway will not fit.
Safe Single-File Access
A stable, code-referenced surface with fall protection for single-file passage.
Routes Around Obstructions
The walkway is routed to fit between equipment, along walls, and around obstructions.
Full Guarding
42-inch guardrails and toe boards engineered to align with OSHA 1910.29 within the tight envelope.
Connects to Standard Walkways
Ties into standard walkways, platforms, and catwalks to complete the access route.
Bolted & Reconfigurable
Installs in confined areas and reconfigures as the layout changes — no welding.

Why Choose Modular Aluminum T-Slot Construction
Modular aluminum T-slot catwalks and walkways bolt together without welding and reconfigure without cutting — giving you a purpose-engineered elevated route today that adapts through every equipment change, line re-lay, and facility expansion without scrapping steel. Built from 45 Series T-slot extrusion with an integrated 40mm round handrail system, the structure will not rust, flake, or require repainting, presents a clean professional appearance, and ties directly into our stair, platform, crossover, and guarding ecosystem. Open grating decking sheds debris and lets light through to the floor below, lightweight aluminum eases installation and reduces imposed loads, and every walkway is engineered and manufactured in-house in Auburn Hills, MI so the route fits your facility exactly rather than forcing your operation to fit a catalog.
Design & Engineering Considerations
How our engineers approach each catwalk and crossover project.
- Tight-route survey - We map the constrained space, obstructions, and clearances the walkway must fit.
- Width and routing - Width and path are engineered to fit the envelope while keeping passage safe.
- Structural design - Supports and decking are sized for pedestrian loads in the constrained space.
- Guarding fit - Guardrails are configured to protect within the tight envelope.
- Integration - Connections to standard walkways and platforms complete the route.
Safety & Compliance Considerations
Every structure is engineered to align with OSHA 1910.28 walking-working-surface and 1910.29 guardrail criteria; installed compliance is verified with your safety authority.
- 42-inch guardrails, mid-rails, and toe boards engineered to align with OSHA 1910.29 within the envelope.
- Slip-resistant decking selected for the environment and route.
- Passage width engineered to keep single-file travel safe.
- Access geometry engineered to align with OSHA 1910.25 and related criteria.
- Clearances in the tight route engineered and verified with your safety authority.

Frequently Asked Questions
Common questions about narrow access walkways design, configuration, and compliance.
What is a narrow access walkway?
It is a reduced-width guarded walkway engineered for safe single-file access along tight spaces — between closely spaced equipment, along walls, through confined chases, and around obstructions — where a standard-width walkway will not fit.
How narrow can it be?
Width is engineered to the tight route while keeping single-file passage safe. We set the minimum practical width for the space and use, balancing fit against safe travel and code requirements.
Can it route around equipment and obstructions?
Yes. We route the walkway to fit between closely spaced equipment, along walls, and around columns, ducts, and other obstructions, holding the required clearances.
Does it connect to standard walkways?
Yes. Narrow segments tie into standard-width walkways, platforms, and catwalks to complete an access route where space tightens and opens back up.
Are narrow access walkways OSHA compliant?
They are engineered to align with OSHA 1910.29 guardrail and 1910.25 access criteria within the constrained envelope. Installed certification is verified with your safety authority.
Can it be reconfigured later?
Yes. The bolted T-slot aluminum structure installs in confined areas and reconfigures with hand tools as the layout changes.
