Abstract
A metallic frame fire-stop is set forth formed of planar-like reinforced rib construction including necked-down terminal end portions with integral interlock elements for twist-fit locking engagement with typical metallic studding, as commonly utilized in commercial construction. The width of the fire-stop members are dimensioned to equal those of metallic studding with the neck-down terminal end portions dimensioned to nest within the metallic studding's vertical legs. The so formed fire-stop accordingly require no accessory fastening elements for securement to the aforenoted studding.
