Guardrail
Braided wire rope and stanchions form a perimeter guardrail. Inside this Protected Zone, workers and visitors need no additional fall-protection equipment.
Fall Protection for High-Rise Construction
The 3-in-1 system engineered for safety.
Metro Safety Rail combines guardrail, travel restraint, and fall arrest in one engineered system for multi-storey concrete construction.
Engineered to meet the requirements of CSA Z259.16, ANSI Z359.6, and OSHA 1926.502Engineered by Greg Small, P.E., P.Eng., M.Eng.
One system, three protections
Guardrail · Travel Restraint · Fall Arrest
Travel Restraint
When a worker is between the guardrail and the leading edge, they tie off to an energy-absorbing horizontal lifeline, restrained from reaching the edge. Multiple workers can tie off on each lifeline.
Fall Arrest
If a worker’s centre of mass could go beyond the leading edge, the energy-absorbing lifeline arrests the fall — by design the system absorbs energy to help minimize injury.
The solution
A passive perimeter that supports active construction.
The MSR system is designed for the realities of concrete towers: slab edges, envelope sequencing, floor-to-floor movement, and changing site access.
Slab-edge confidence
Installed back from the slab edge so most workers remain inside a passive guardrail perimeter while the envelope team can keep moving.
Fall arrest design
End and corner posts are designed to bend during a fall event, helping absorb energy and reduce cable forces below 6 kN.
Rental flexibility
Above-slab components can be rented for the project duration and moved between floors. Cast-in inserts are purchased for the slab.
How it works
Cast in before the pour, reused floor to floor.
Our capital-efficient model keeps costs low: the upfront purchase includes everything needed to get started, and the reusable above-slab components are rented for their days in service. The rail can be removed from lower floors and redeployed to upper floors as construction progresses — simplifying operations so projects run safely and efficiently.
Cost Effective | Easy to Install | Simple to Use
- 01
Cast-in
Polyurethane rail inserts and reinforcing “spiders” are cast into the slab before the pour.
- 02
Set up the rail
After curing, caps are removed, stanchions inserted, braided wire rope tensioned, and a toe board installed — forming the perimeter guardrail.
- 03
Protected Zone
Inside the guardrail is a Protected Zone where no additional fall-protection equipment is required.
- 04
Beyond the edge
Beyond the guardrail, two Energy Absorbing Horizontal Lifelines per leading edge provide travel restraint and fall arrest. Site-specific training is required beyond the guardrail; Competent Person Training is included.
Delivery & Staging
Engineered to ship and stage
Transport containers are engineered and certified for overhead hoisting.
Braided wire-rope lifelines, stanchions, and hardware can be safely and securely staged wherever needed.

Services
Support from layout to rescue planning.
Procedures and fall protection plan
Installation procedures, erection procedures, and a written fall protection plan are provided with the system.
Training and quality checks
Training is included for personnel laying out, setting up, and using the MSR system, with periodic quality checks on installations.
Fall-protection training (QFPE / QFPS)
Course overviews and syllabi for the QFPE and QFPS programs are available on the Resources page.
Engineering and consulting
Custom engineering, consulting, and rescue planning can be quoted when a project needs additional support.
Project review
A clear path from drawings to install-ready scope.
General contractors and concrete teams need quick answers before a slab-edge safety system is added to the plan. MSR reviews the project information, confirms fit, and turns the drawing set into a practical scope for quoting and coordination.
Share the project
Send slab plans, building height, schedule context, and the preferred team contact.
Review the drawings
MSR checks slab layouts, edge conditions, envelope access, and installation constraints.
Confirm the scope
Define rental rail, purchased inserts, floor movement, training, and service needs.
Coordinate the work
Track submittals, installation status, usage records, quote updates, and invoices.
Testimonials
Trusted on high-rise concrete sites.
“We found the solution easy to install and fit into our construction process without any issues or delays. Once installed the system allowed our team to work freely and effectively in a safe environment. The rail system was cost effective and allowed flexibility of use without the need of additional safety or fall arrest products.”
“I’ve seen the design changes and improvements to the now-patented, engineered system that makes this a great solution to address safety, ease of use and functionality in the construction process. I would not hesitate to recommend Dale and the Metro Safety solution.”
