18-inch Diamond Hazard Marker

This Lyle OM1-2-18HA sign is an aluminum diamond marker measuring 18 inches on each side. It carries a yellow and black hazard symbol with no printed text. Mounting holes allow attachment to posts, fences or walls. The unit suits facility managers, grounds crews and traffic-safety teams who need a durable, high-visibility warning device.

Practical Limits of the Aluminum Sign

The marker is a passive device; it requires ambient or vehicle light to be seen and does not illuminate itself. Aluminum can dent or bend on impact, so the sign is not suited for locations with frequent vehicle contact. The fixed 18-inch diamond size may not meet every local ordinance that calls for larger or differently shaped markers. Buyers who need reflective sheeting, internal lighting or a different legend should select another product.

Questions about this item

What does the 18-inch diamond size mean for placement?

The 18-inch diamond dimensions match the standard OM1-2 hazard marker size, fitting typical post or wall mounts used for roadside and facility marking.

How does the aluminum construction hold up once installed?

The aluminum sign resists rust and fading, so the yellow and black graphics stay visible through sun, rain and temperature swings without warping.
