	Allows free air flow through trunking. Up to 4 hour fire resistance. Perfect solution for retrofit of cables. Economical solution. Rapid Installation BS476 Part 20: 1987
Description The sub-division of compartments in a building, if effectively fire-stopped, will prevent the spread of fire and smoke through fire-resisting and separating elements, thereby reducing the risk of and fire damage to the primary building structure. Electrical penetrations, such as metal trunking, by necessity breach these elements. It is therefore essential that fully tested products/systems are installed to maintain the integrity and insulation of the compartment wall or floor whilst providing adequate thermal insulation to the penetrating services. Consisting of a pre-fabricated metal frame which contain compressed intumescent fillers, ASTRO Clamp has been designed to stop fire-stop cables, cable trays, trunking and pipes. They are able to accommodate multiple penetrations either isolated or grouped together. Tested in accordance with BS476 Part 20: 1987, ASTRO Clamp has achieved integrity and insulation ratings in excess of 120 minutes in both wall and floor configurations. The intumescent fillers contained within the ASTRO Clamp will intumesce (expand) at about 115°C forming an insulating char. Areas Of Use Suitable for all metal cable trays where they breach fire compartment floors and walls. Under raised access floors where cabling is often abundant, i.e. computer, switch and security rooms. Retrofit: Perfect for installations where frequent cable alterations occur.
