An apparatus for reinforcing adjacent parallel spaced apart wooden structural members. Each of the structural members extends between first and second edges. The apparatus comprises a rigid member having first and second ends and being sized to extend between adjacent first and second structural members. The apparatus further comprises a first socket connected to the first end of the rigid member sized to receive a first edge of the first structural member therein and a second socket connected to the second end of the rigid member. The second socket is sized to receive a first edge of the second structural member corresponding to the first edge of the first structural member therein.
