Typical Handrail Bracket Attachment

Due to structural requirements for Handrail Brackets, proper attachment is critical to assure safety. While there are other methods of attachment, what we show here are the most typical.

Check with your fastener supplier regarding Epoxy Anchors and Anchors for hollow block.
In hollow wall applications, Handrail Brackets must be fastened to wood studs or appropriate blocking must be provided to meet structural requirements.
