How the Layher advance guardrail system works
The Layher advance guardrail consists of two basic components –
advance guardrail post and telescoping guardrail. The assembly post
a) or b) must be used depending on local regulations.
a. Advance guardrail post with connection for telescoping guardrail
at 1 m height
b. Advance guardrail post with connection for telescoping guardrail
at 0.5 m and 1 m heights
c. Advance telescopic guardrail of aluminium

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

To prevent unintended slipping of
the advance guardrail post, fit a rear
guardrail at the level of a snap-on
claw.
