The Most Versatile Roof Guardrail Fall Protection System on the Market

All roofs over 10′ have falling hazards to eliminate, but each is different. To adapt to all risk situations on all roofs, Delta Prevention has developed two configurations using the same patented recycled rubber base. These two configurations can be used independently on the same building or can be combined to maximize their benefits.


Our classic roof guard rail is a linear type configuration allowing you to secure a minimum of 10 feet to your entire perimeter without any full height return. An installation more in harmony with the visual aspect of the building to be protected.


Much more compact, this guardrail fall protection system is ideal configuration when floor space is reduced between the units to be protected and the parapet. A full height return of 5 feet is required every 40 feet when there is no parapet.
