Pensacola, Florida 32504

Dear Mr. Jones:

This is in response to your letter of October 22, 1981, concerning the use of Southern Yellow Pine versus the use of Douglas Fir.

Please be advised that we no longer specify what species of wood should be used for speciality system designed scaffolding. Instead, when the plank span is extended to 10' 6" the planks must be rough full-dimensioned 2" x 12' planks of Dense Select Structural Grade or equivalent.

I hope this explanation will answer your question. If I can be of further assistance, please contact my office at (202) 523-7144.
