Length of strap is different for each tank diameter. ♦ Maintain proper distance between anchor points on each side of the tank : • Tank diameter plus one deadman width for concrete deadmen. 10 • Tank diameter plus 12" to 24" for concrete anchor pad. ♦ Anchor points must be aligned with designated ribs (b.4) *1 ", ♦ Place anchor straps in the strap guides over the designated ribs ( ).
