The International Residential Code (IRC) requires that decks be designed to withstand both vertical and lateral loads.
This 2015 code allows for tension ties to be attached to the deck joist then fastened directly to an interior sill plate, wall plate or stud – all from the outside.
- Installed in four locations along the length of the ledger
- One within 2' of each end of the ledger with two more evenly spaced between.
- Install the fastener first and then add the bracket.
- No need to access the interior the house.
- Designed to resist 750 pounds in tension per location.
The Lateral Tension System is approved for the five most common installation conditions:
- Condition A: Sill Plate or Wall Plate Behind Ledger
- Condition B: Sill Plate or Wall Plate Directly Below Ledger
- Condition C: Sill Plate or Wall Plate 2” – 5” below Ledger
- Condition D: Wall Stud in line with Deck Joist
- Condition E: Wall Stud between Deck Joists
