Perimeter Clamp System
Meets OSHA Requirement 1926.502(b)
The Perimeter Clamp is an OSHA-compliant, leading-edge fall prevention solution engineered for both flat roof edges and parapet walls. Ideal for new construction and retrofit applications, this versatile system allows safe, unrestricted work right up to the roof edge without the need for personal fall restraint systems. The clamp fits parapets ranging from 8″ to 24″ wide, and its ergonomic tensioning handle allows one-person, tool-free installation in minutes. By eliminating the limitations of visual warning lines, the Perimeter Clamp improves crew mobility and increases productivity by up to 50%.
Built for durability and performance, the Perimeter Clamp features zinc-plated components and powder-coated stanchions to resist weathering and wear. It’s designed for strength with oversized clamp pads, 1.25″ tubing, and a reinforced rubber-coated handle for greater clamping force and long service life. The system can also be lag-bolted to wood caps when clamps aren’t suitable, avoiding any clamp protrusion into the rooftop work area.
