Guardrails

Standard guardrails consist of a top rail, located 42 inches above the floor, and a mid-rail. Screens and mesh may be used to replace the mid-rail, so long as they extend from the top rail to the floor.

• Top-rail must be at a height of 39 to 45 inches for construction and 42 inches for all other applications.
• Mid-rails must be at a height of 21 inches.
• Top-rails must be able to withstand 200 lbs. of outward or downward force.
• Mid-rails must withstand a force of 150 lbs.
• No steel or plastic banding is allowed to be used for a top-rail.
• Wire rope top-rail must be flagged every 6 feet.
• All wire rope used for perimeter protection must be at least 3/8 inch nominal diameter.
• Manila, plastic, or synthetic rope rails must be inspected frequently.
