Mason 30SMCC ceiling hanger included in UL certified construction
We are excited to let you know that our 30SMCC spring ceiling hanger is now included in the UL Fire rated assembly M553. This certified design includes I-joists, wood truss, and lumber construction.
We have also completed acoustical tests at the prestigious NRC Lab in Canada and are pleased to report an STC 60 and IIC 54.
Here are photos from our fire test we thought you might find interesting.
