Allowable loads shown are for sin

)
TD models - install TD holdown raised off of bottom
p
late if the BH dimension is less than end distance dimension.
6
)
Deflections are derived from static, monotonic load tests of devices connected to DF wood members and consider both the deflection of
the holdown and cross
g
rain crushin
g
of the wood

ost.

The desi

due to device eccentricit

when a

licable.

The TD/TDX ma

increase deflection. Reference
