The post of the AGR rail can be fitted and dismantled
by an erector from two positions:
1. Fitting/dismantling from above
2. Fitting/dismantling from below
It must be ensured that both claws of the advance
guardrail snap in completely and that the telescoping
guardrail is attached using the tilting pins.
