Reviews
Fixed the rigid plastic version with cable ties onto fencing beside the excavation. Feels solid and hasn’t moved, even when machinery’s rumbling past. Very reliable for safety.
Applied the vinyl sticker to a hoarding near the dig. It’s stuck well and hasn’t started peeling, despite foot traffic and muddy boots nearby. Simple and effective warning.
Picked the Correx board for a short-term excavation area. Lightweight yet sturdy, and it’s stayed in place through a few rainy spells. Does its job properly without any fuss.
Used the rigid plastic sign next to a deep trench and it’s really held its own. Clear, bold lettering that’s easy to spot even in dull light — exactly what’s needed for warning passers-by.
