Updated R-Control Technical Bulletin No. 2029 – Roof Cantilevers

We are pleased to announce an update to R-Control Technical Bulletin SIP No. 2029 is now available.  The updated R-Control Technical Bulletin adds a new Load Design Chart #9A for cantilevered R-Control SIPs when connected with double 2X splines.

The use of double 2X splines increases the capacity of R-Control SIP cantilevers above the existing Load Design Chart #9 which covered R-Control SIPs connected with surface/block splines.
