The Simpson Strong-Tie DTT2SS Type 316L Stainless Steel Tension Tie is a safe, cost-effective way to attach deck-railing posts to the deck framing. Because the post is tied back into the deck joists, rather than to the rim joist alone, the connection is stronger than typical through-bolt installations and complies with IRC and IBC code requirements regarding handrail and guardrail post connections for decks. The DTT2SS also complies with the new IRC requirements for laterally tying the deck to the house. Additionally, the versatile DTT2SS is load rated as a holdown for light-duty shearwalls and braced wall panel applications. The DTT2SS fastens easily to a single 2x joist or stud using Simpson Strong-Tie® Strong-Drive® SDS screws (included) and accepts a 1/2" machine bolt or anchor bolt.
The DTT2SS is ideal for two critical deck connections:
Guardrail-Post Connection
- Ties the guardrail post into deck framing
- Stronger and safer than nails, lag screws or bolts
- Meets provisions set in the International Residential Code® (IRC) for guardrail reinforcement (Table R301.5)
- Single post-to-deck connection tested for the concentrated load specified in ICC-ES acceptance criteria for Handrails and Guards (AC273)
Lateral-Load Connection
- Ties the deck into the house for a stronger, safer ledger connection
- Helps prevent a common type of deck failure
- Meets provisions set by the 2009 International Residential Code® (IRC) for lateral deck-to-house connections (R502.2.2.3)
