Nu-Guard™ 31 Steel Guardrail Plastic Post Cap

The Nu-Guard™ 31 Steel Guardrail Plastic Post Caps are an optional accessory for all Nu-Guard™ 31 barriers. When impacted the Nu-Guard™ 31 height will change due to the post bolt being able to move in the slot on the back of the post. This feature of the system requires that the top of the post be approximately 25mm higher than the top of the rail after correct installation. To improve safety to pedestrians and cyclists or purely for aesthetic purposes, the plastic post caps are a good way to protect the exposed steel post. The plastic post caps will fit either the Nu-Guard™ 31 ‘roadside’ or ‘median’ barrier.
