Sample Description
(34) 16”x16” wood test boards were delivered to our laboratory on February 26, 2016. Each specimen was made up
of 2”x4” lumber, topped with ½” plywood and 30 lb. felt paper. The specimens were equipped with the flashing and
1-1/4” OD by 4-1/2” long post fastened to a 2”x4” Douglas Fir with 4” long, 5/16” diameter GRK RSS Rugged
Structural Screws. (31) Tests were conducted with a Unirac L-foot (representative of typical L-foot on the market),
and (3) tests were conducted without a Unirac L-foot. Test loads were applied directly to the L-foot for tensile.
Compressive, lateral and resultant test loads were applied to a block attached to the L-foot to represent typical
transfer of load from the rail into the L-foot. When no L-foot was present, the test load was applied directly to the
post. See Figure 1 and Figure 2 for a typical test board.
