I cut out a 10' garage door opening in small commercial buliding(2 story,12" block)
i have put and adequate steel header in place,but somebody told me i am to "tie-in" bothe ends of the header to the masonry... is this a requirement?
Or is this just an option?
Can anybody help me?
Are there any illustrations of this procedure that I can view to guide me in the right direction?
Thank you
