Bolt ties
OBO Bettermann's fire protection bolt ties were fire-
tested according ETAG 001 Part The maximum
load capacity, depending fire resistance periods of
up 120 minutes, was determined for different types
of solid masonry. spread-
ing forces develop and mounting near masonry
edges not required. Taking the occurring
loads for the maintenance electrical functionality
applications and for false ceiling mounting into ac-
count, the determined load capacities for the different
masonry types are absolutely sufficient. These values are documented in
the appropriate test certificates
