Abstract
A horizontal support beam is provided with a vertical connection bracket, constructed to attach the horizontal beam to a vertical column of a storage rack system. The vertical connection bracket includes a plurality of protrusions positioned to eliminate some of the gaps that can exist between the bracket and column. The vertical connection bracket can be an L shaped angle bracket. An inside surface of the first arm can include a plurality of protrusions, which can be formed by pressing dimples into the first arm, to help ensure a tight, contacting fit between the inside surface of the first arm and the vertical column.

A structural support beam, comprising:
- an elongated support member having a front first support member end, a rear second support member end, and a central portion extending in a forward first direction from the second support member end to the first support member end;
- a connection bracket extending forward from the first support member end in the first direction, the connection bracket having a generally L shaped cross section defined by a sidewise facing first arm and a forward facing second arm joined at a vertex, the vertex elongated in a vertical second direction perpendicular to the first direction, the first arm extending forward from the vertex in the first direction and the second arm extending sideways from the vertex in a third direction, perpendicular to the first and second directions;
- the first arm having a sideways facing connection surface facing in the third direction and defining a sideways facing connection plane perpendicular to the third direction;
- the second arm extending sideways from the vertex in the third direction, and having a generally flat forward facing engagement surface defining a plane perpendicular to the first direction,
- the first arm including at least one bolt receiving hole therethrough, adapted to receive a bolt to secure the first arm to a structural column;
- and
- the second arm having at least one protrusion portion formed into the second arm as a deformation of the generally flat forward facing engagement surface, the protrusion portion of the second arm extending in the first direction from the engagement surface, the protrusion located entirely within a periphery of the engagement surface and forward of the plane of the engagement surface.

A support structure, comprising:
- a vertical column extending in a vertical direction and having a contact surface defining an engagement plane;
- a horizontal support member having a first support member end, a second support member end, and a central support portion therebetween, the horizontal support member extending in a first horizontal direction, perpendicular to the vertical direction, from the second support member end to the first support member end;
- a first connection bracket, elongated in the vertical direction, connected to the first support member end, the first connection bracket having a first arm and a second arm perpendicular to the first arm, the first and second arms joined at a vertex extending in the vertical direction, the second arm having an engagement surface defining a first plane facing the first horizontal direction, and having a periphery of the second arm, the first arm extending from the vertex in the first horizontal direction;
- the second arm formed into at least one protrusion extending in the first horizontal direction from the first plane of the engagement surface;
- and
- the engagement surface of the second arm facing the contact surface of the vertical column with a gap therebetween, and the at least one protrusion located within the periphery and extending in the first horizontal direction across the gap, from the first plane of the engagement surface to the engagement plane of the vertical column, and the protrusion pressed against the engagement plane of the vertical column.

- an elongated support member having a first support member end, a second support member end, and a central portion extending in a first direction from the second support member end to the first support member end;
- a connection bracket extending from the first support member end in the first direction, the connection bracket having a generally L shaped cross section defined by a first arm and a second arm joined at a vertex, the vertex elongated in a second direction perpendicular to the first direction, the first arm extending from the vertex in the first direction and the second arm extending from the vertex in a third direction, perpendicular to the first and second directions;
- the first arm having a connection surface facing the third direction and defining a connection plane perpendicular to the third direction;
- the second arm extending from the vertex the third direction, defining an engagement surface perpendicular to the first direction,
- the first arm including at least one bolt receiving hole therethrough, adapted to receive a bolt to secure the first arm to a structural column;
- and
- wobble reduction means on the engagement surface for reducing wobble between the engagement surface and a support column, when the first arm is bolted to the support column and the engagement surface is drawn against the support column.
