Bollards have been around for centuries, originally used for mooring ships or securing ropes in port areas. Over time, their purpose has evolved significantly. In contemporary urban settings, they are viewed not only as protective barriers but also as artistic elements that contribute to the character of a place. From simple steel posts to elaborately designed structures, architectural bollards come in an array of shapes, sizes, and materials, reflecting the site’s history and cultural context.
Split sleeve repair clamps find applications across multiple industries. In the water and sewage sector, they are used to repair leaks in vital infrastructure without the need for extensive excavation or replacement, thereby conserving both time and resources.

The Boston area experienced 62 events in 2021 (down from 212 in 2018). As of 2022, local utility company Eversource is replacing 38,000 maintenance hole covers, starting in high-traffic areas, with a safer design. A rail allows the cover to lift up to 4 inches (100 mm) and let gases escape, but prevents it from flying into the air and damaging buildings or cars or injuring pedestrians. In some places where road salt is not a concern, the covers have vents to let gases escape. To prevent and mitigate safety problems, the company is also installing monitoring equipment to detect dangerous gases and fires, and increasing inspection frequency.[15]
