GUARD RAILSYSTEMS
System Sizing: How do I size a guard rail system?
The following steps show how to size a single-sided,
three-sided, and four-sided guard rail system:
Step 1: Determine the stage length and width.
Step 2: Determine whether guardrail system is one-, two-, three-, or four -sided.
Step 3: Read across the row to determine component requirements.
Step 4: If ordering a three- or four-sided system, order two ERT-N for 12"
and 14" wide stages, and two ERT-W for all stages 20" wide or greater.
Note: If ordering a two sided system, double the single sided component requirement.
