You have two options for ordering the fire-stop material:

1. With initial busway purchase. Use the product numbers listed above and the fire-stop material will be shipped in a specially marked box directly to the job site with the busway. 2. Through empower or an authorized ABB Silicones Distributor. Recommended for fill-in (if needed) after initial purchase. This information is provided as a guideline for typical fire stop systems. If you have an annulus (or opening) greater than 1” beyond the busway enclosure, you will need to determine the proper amount of fire-stop material based on the illustration on this page. Quantities are based on application of recommended amount of material; more may be required if over-application occurs.
