THRU-JOIST™ brackets
enable holes to be cut up to 121mm diameter
in flooring joists to allow services to run
through the mid floor and other enclosed
areas, without affecting the strength and
stiffness requirements of a joist under NZS
3604:1999 and AS 1684.2-2006 (For Radiata
Pine up to and including stress grades F8).
No limitation on where THRU-JOIST™ brackets
may be installed along the length of joist.
Multiple THRU-JOIST™ brackets
may be used on the same joist (refer fixing
note).
Alternative BRANZ Appraised
Solution to NZS 3604:1999 and Australian Standard
AS 1684.2-2006.
THRU-JOIST™ brackets are
a very cost effective, simple to install building
method to allow services to run through joists.
