Continue to install Blocks/Planks until through opening is completely full, and blocks/planks are firmly packed together. Block/Plank can be re-sized in the field as needed provided the 5 in. (130mm) dimension is maintained through the opening. No compression is necessary. 3. Install Fire Barrier Rated Foam FIP 1-Step between the Blocks/Planks and the periphery of the opening and between Blocks/Planks and penetrants. Foam to be installed full depth of the Blocks/Planks. 4. Check for any openings between Blocks/Planks, framing, and penetrating items. Fill any visible openings with the required depth of Foam. Consult individual UL systems for Foam depth and location requirements. 5. To remove the Blocks/Planks, gently pull them out and place on a clean surface. After penetrants are routed through, or removed from the opening, replace the Blocks/Planks, making sure that they are firmly packed and fully filling the opening.

Install Fire Barrier Plug within the opening flush with top surface of floor or both sides of wall. 2. To fit smaller openings, Plugs may be compressed to size, or a wedge may be cut from Plug to reduce size. 3. Plugs may be cut to fit around cable penetrants 4. Holes may be cut/punched through Plugs to route cables directly through. 5. Fill all voids and interstices of cables with Fire Barrier Rated Foam FIP 1-Step, full depth of the Plug. Limitations: Additional firestop may be necessary for non-metallic penetrants. Consult individual UL systems for firestop requirements. Maintenance Inspection: Installations should be inspected periodically for subsequent damage. Damaged blocks, plugs, or planks shall be replaced. Retrofit: Penetrants may be added or replaced by simply removing and replacing blocks, planks, or plugs and foam as required.
