NEW! The DTT2Z 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 DTT2Z also complies with the new IRC requirements for laterally tying the deck to the house. Additionally, the versatile DTT2Z is load rated as a holdown for light-duty shearwalls and braced wall panel applications. The DTT2Z fastens easily to a single 2x joist or stud using Simpson Strong-Tie™ Strong-Drive™ screws (SDS) (included) and accepts a 1/2" machine bolt or anchor bolt.
Material: DTT2Z - 14 gauge.
Finish: DTT2Z - ZMAX™coating.
Installation: Use all specified fasteners.
A standard cut washer must be installed between the nut and the seat. Simpson Strong-Tie SDS screws install best with a low speed high torque drill with a 3/8" hex head driver. Bolt holes shall be a minimum of 1/32" to a maximum of 1/16" larger than the bolt diameter (per NDS, section 11.1.2). Locate on wood member to maintain a minimum distance of seven bolt diameters, distance is automatically maintained when end of wood member is flush with the bottom of the holdown. Bolts should be snugly tightened.ORDER BOLTS, NUTS, AND WASHERS HERE.
