GRIZZLY proposes an effective guard rail system. It is compact and economic, made of two parts, the post and the clamp.

All you need to do is tighten the clamp on the parapet wall and fix it mechanically, then insert the post. Join the posts using 2 X 4 X 8’ lumber.

If the use of clamps is not possible, the posts could be used alone, by screwing them directly to the parapet wall or use the guard rail wall mount bracket (sold separately).
