For correct functioning of the guard trac™ or guard trac™ plus guardrail, and in order to complete the
fall prevention safety setup, you must meet the following requirements relating to guardrail installation
surfaces and structures.

6.1. Roof load distribution table

The roof on which the guard trac™ or guard trac™ plus guardrail is installed must be resistant to
support the additional weight of the guardrail as indicated in the load distribution table below:
