The Envirograf multi-purpose square box is the most versatile of its kind available and has been specifically designed for most installations where services pass through fire barrier ceilings, floors, and walls. It can be surface – mounted or recessed.

Advantages

  • A versatile solution to the problem of services passing through walls, floors and ceilings, offering up to 4 hours protection
  • Detachable face plate allows for the box to be fitted in tight corners
  • Adjustable brackets can be bent flat to fit flush against flat surfaces such as walls or ceilings, or kept at a right-angled position to fit in corners

Application Instructions 

For standard open areas, simply place the box over the services, use the smoke seal if required, and screw into position. If the services are already in place, remove the detachable section, fix the ā€˜Uā€™ section first then slide back the detachable section and fix the smoke seal if required.

When the unit is flush against a ceiling, floor, wall, or corner simply bend the fixing brackets flat and screw into position. When using multi-purpose box to fit around existing services in a tight corner, simply remove the detachable section and fix the ā€˜Uā€™ section into position. Fixing brackets can be bent flat if required. Replace the detachable section and fix to finish. Insert the smoke seal if required.
