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. 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. The fire pro-
tection bolt ties are screwed directly into the drill hole. These values are documented in
the appropriate test certificates.
There need for additional anchor. The bolt tie equally suitable
for cracked concrete ceilings.
