What is a temporary guardrail system?
A guardrail is passive fall protection: a physical barrier at the edge that stops a fall before it starts. There is nothing for the worker to put on, clip into, or remember. Temporary systems install without welding or drilling, hold the edge for the length of the job, and come down clean when the work is done. That combination is why guardrails are the first choice for edge protection on roofs, decks, and openings.
Passive protection sits at the top of the hierarchy of controls
Personal fall arrest depends on a worker wearing a harness correctly, clipping to the right anchor, and having enough clearance to arrest a fall. A guardrail removes every one of those variables. It protects everyone on the deck for the whole shift, with no training-dependent step in between. When a guardrail is feasible, it is the stronger control, and it is the one OSHA and the hierarchy of controls point to first.
Tie Down guardrail systems
WebRail
A portable, tensioned guardrail and fall-arrest system built for leading edges where a fixed rail is not practical.
Zip Rail
A modular steel pipe-and-fitting railing that assembles into a permanent-feeling temporary rail for roof perimeters, stairs, platforms, and openings.
Free-standing weighted-base guardrail
Counterweighted bases sit on the surface and hold standard rail sections with no penetration, ideal for flat commercial roofs.
Parapet clamp and specialty rails
Clamp-mounted rail for parapet walls, ladder guardrail corrals, and rails for skylights and floor holes round out the system.
Non-penetrating: no roof damage, no warranty risk
Weighted-base and clamp-mounted systems protect the edge without drilling the roof membrane. That keeps the roof watertight and keeps manufacturer warranties intact, which matters on new and recently re-roofed buildings.
Buy or rent?
Buy when you protect the same edges project after project and want the system on hand. Rent when a job has a defined start and finish, when you need extra footage for a short push, or when you want to trial a system first. M Squared Safety does both, nationwide across the U.S. and Canada. Call 949-954-6581 and we will size the system to your edge.
OSHA compliance
Under OSHA 29 CFR 1926.502(b), a guardrail top rail must sit 42 inches, plus or minus 3 inches, above the walking surface and must withstand at least 200 pounds of force applied in any outward or downward direction, without deflecting to less than 39 inches. Midrails are required where there is no wall or equivalent between the top rail and the surface. Tie Down guardrail systems are built and tested to meet these criteria.
Where crews use temporary guardrails
- Rooftop perimeters and leading edges
- Roof hatches and skylights
- Mezzanines and elevated platforms
- Loading docks and dock edges
- Floor holes, stair openings, and pits
- Warning-line and controlled-access zones
Industries we serve
Warehouse and distribution
Mezzanine edges, pick modules, and dock openings need permanent-feeling temporary rail that installs without drilling the floor. Free-standing and clamp systems hold the edge and move when the layout changes.
Manufacturing and industrial plants
Platforms, pits, mezzanines, and machine access points get guarded with modular Zip Rail and weighted-base systems, protecting maintenance and production crews on every shift.
Facilities, building maintenance, and HVAC
Rooftop equipment access, roof hatches, and skylights are the most common fall points on a commercial building. Non-penetrating rooftop rail guards them without touching the membrane or the warranty.
Roofing and construction
Leading edges and roof perimeters get fast, compliant guardrail that installs and strikes clean between phases.
Utilities and energy
Catwalks, transformer platforms, and plant walkways use guardrail as passive protection so crews are covered without a harness on every task.
Temporary guardrail FAQ
How tall does an OSHA guardrail have to be?
The top rail must be 42 inches, plus or minus 3 inches, above the walking surface and must withstand at least 200 pounds of force without deflecting below 39 inches, per 29 CFR 1926.502(b).
Do these guardrails damage the roof?
No. Weighted-base and clamp-mounted systems are non-penetrating, so they hold the edge without drilling the membrane or voiding a roof warranty.
Can I rent temporary guardrails?
Yes. Tie Down guardrail systems are available for sale or rental nationwide across the U.S. and Canada. Call 949-954-6581 for availability.
Does OSHA prefer guardrails or personal fall arrest?
Where a guardrail is feasible, it is the stronger control. As passive protection it guards everyone on the deck without a training-dependent step, which places it above personal fall arrest in the hierarchy of controls.
What are WebRail and Zip Rail?
WebRail is a portable, tensioned guardrail and fall-arrest system for leading edges. Zip Rail is a modular steel pipe-and-fitting railing for roof perimeters, stairs, platforms, and openings.
Are these systems reusable?
Yes. Temporary guardrail systems are designed to install and remove cleanly and to be reused across projects.
