Installation Techniques,

cont.

Plugs

1. 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.
