Roof Guardrail

Diversified Fall Protection’s free-standing, non-penetrating guardrail  is safer and lighter than most comparable roof safety railing systems. Other portable guardrail systems have larger spacing between each railing, and heavier bases weighing 100 pounds and more as compared to 57 lbs. for LORGUARD™.

One of the major uses of portable safety railing systems is perimeter guarding along the edges of roof tops. Prudent buyers recognize that because of the wider spaces between each rail, they are buying ‘AIR.’ Furthermore, most engineers would agree; the less weight you place on a roof structure, the better. Roofs are designed for wind, rain and snow loads, not the addition of hundreds of extra pounds of steel.

An ideal rooftop fall protection solution, LORGUARD is available in 6, 8” and 10’ sections, with a standard, safety yellow powder-coated finish or custom colors upon request. LORGUARD rooftop guardrail rail sets up quickly, making it ideal for temporary applications. We've also engineered the base plate design to withstand high wind gusts, and many of our clients select LORGUARD as a permanent roof fall protection solution. If you are looking for a non-penetrating guardrail solution to mitigate the fall hazards posed by roof edges, skylights, and roof hatches on built-up, standing seam, concrete, or membrane roofs, LORGUARD will keep your personnel safe and your facility in full compliance with OSHA regulations. The secret to the LORGUARD roof top rail system is our ergonomically designed base plate (sold separately). Almost HALF the weight of other systems, your workers can carry 2 base plates making setup and tear-downs even faster! Flexible positioning of the base plates keeps you in control around corners and roof top obstructions.
