	** NOTE TO SPECIFIER ** Latchways PLC; Constant Force Fall Protection system and freestanding ManSafe Guardrail products. . This section is based on the products of Latchways PLC with North American offices, located at:
	Hopton Park Devizes, Wiltshire UK SN10 2JP Tel: 011 44 1380 732700 Fax: 011 44 1380 732701 Email: info@latchways.com Web Site: www.latchways.com [ Click Here ] for additional information.
	Latchways is the world leader in the manufacture and design of fall protection systems. Over the years the company has continuously researched new ways of improving worker safety at height while aligning its product range to the evolving needs of the marketplace and regulations governing it. Latchways ManSafe fall protection devices are used around the world on tall buildings and structures as diverse as office blocks, industrial units, leisure and retail complexes, telecommunications towers, bridges and electricity pylons. This specification includes the Constant Force fall protection system and the freestanding ManSafe Guardrail system that provides a comprehensive protection solution for worker safety at height. The Constant Force fall protection system is suitable for sloped roofs and with all roof surfaces. The ManSafe Guardrail system is quick and easy to install and can be used on virtually any flat roof surface. Importantly, the system's ergonomic counterbalances hold the Guardrail firmly in place without any damage to the integrity of the roof surface itself. Aesthetics and installation flexibility are crucial factors in the rooftop safety system design. The use of high quality materials gives the assurance of strength while also establishing a visual subtlety that won't conflict with the appearance of the building on they are used. Similarly, the wide range of available components enables the system layout to be configured to ideally suit the collective protection need. .
