  1. Residential Deck Safety Safety Code requirements for attachment of the railing system to the deck.

  2. Insert picture of high deck with wood railing system in this slide.

  3. Insert picture of high deck with lots of people (picture from our website).

  4. Insert picture of a collapsed railing system.

  5. Look around your neighborhood

  6. International Residential CodeIRC 2003 Tables R301.4 and R301.5 specify a minimum concentrated live load capacity of 200 lbf for handrails and guardrails. Insert the tables into this slide.

  7. International Building CodeIRC 2000 Section 1712.1 & 1714 specify that: - the “structural unit and connections” shall be tested with a factor of safety of 2.5.

  8. International Building CodeIBC 2000 The published application of these safety code requirements is that: the guardrail post connection must successfully withstand a minimum applied load of 500 lbf (200 lbf X 2.5).

  9. In wood deck construction, there are 4 basic methods used for attaching the rail post: • Rail post bolted or screwed to the rim joist • Wood blocking behind and next to the railing post • Sheet metal plates on top of the joists • Structural metal brackets that provide an attachment in shear to the deck joist

  10. Rail Post bolted to Rim Joist Fails at less than 200 lbf

  11. Wood Blocking for Structural Support Fails at less than 200 lbf

  12. Sheet Metal Plates nailed to Joists • Failed testing at Virginia Tech Wood Products Lab • Not ACQ Compatible

  13. There is only one methodof attachment that is Safety Code Compliant: A Structural Attachment in Shear

  14. Only DeckLok is : • Designed for wood deck structural connections • Tested successfully at an ICC Certified Testing Lab • Available in Stainless Steel

  15. Attachment in Shear
