Questions & Answers

How many individual ties do I need to use on a deck with a 22' ledgerboard?

How many individual ties do I need to use on a deck with a 22' ledgerboard?
Asked by: Maria
The code only says 4 are needed. 1 within 2 feet of each end then evenly space the other two. Strange enough the code doesn't seem to care if the ledger is 8 feet or 40 feet wide, still only calls for 4 ties.

What is the stress design capacity of each device? I see many reviews stating "code" compliant, but nowhere is there a tension strength specification. Our "code" requires a minimum of 1,500 lb.

What length are the SD connector screws? and What length are the SDWH timber-hex HDG screws? Thank you!
Asked by: Smug
The SD screws are 1-1/2" long. Mine are already installed, but the SDWH screws are at least 7-1/2" long (3" min. into solid framing or studs with a 4-1/2" offset). Both types have hex-heads, so make sure you have the correct adapter for your impact driver/drill.
