Abstract
Abstract A means for attaching one member to another to prevent racking or twisting of the members. It includes a connector which attaches to one member and has a key which fits into a groove in the other member. Several modifications are shown. In one the connector clamps to the first member. In another, both members have grooves which are angularly displaced and the connector has keys which fit into both grooves. A light standard is illustrated. The groove is in the horizontal crossarm and is used to conceal the wire from the pole to the luminaire. The key may be channel-shaped to provide access into the groove for the wire.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
143 words
A connector for attaching cross-arms to standards or luminaires, allowing the passage of wires from said standards to said luminaires, and reducing the racking of the cross-arms comprising a body defined by a pair of parallel sides, a face plate and an upper wall, means on said face plate for attaching said body to said standard or luminaire, said face plate defining an opening into said body, a hollow key extending outwardly of each of said sides, said keys being parallel to each other and transverse to said face plate, each of said sides and said keys defining an opening between said body and said key, the end of each of said keys opposite said face plate defining an opening extending outwardly of said side, said openings in said face plate, said sides and said keys allowing passage of wires through said connector.
Claim 2
Dependent Claim
143 words
A connector for attaching cross-arms to standards or luminaires, allowing the passage of wires from said standards to said luminaires, and reducing the racking of the cross-arms comprising a body defined by a pair of parallel sides, a face plate and an upper wall, means on said face plate for attaching said body to said standard or luminaire, said face plate defining an opening into said body, a hollow key extending outwardly of each of said sides, said keys being parallel to each other and transverse to said face plate, each of said sides and said keys defining an opening between said body and said key, the end of each of said keys opposite said face plate defining an opening extending outwardly of said side, said openings in said face plate, said sides and said keys allowing passage of wires through said connector.
Claim 3
Dependent Claim
23 words
The connector of claim 1 in which said sides are defined by side walls and said keys are channels on said side walls.
Claim 4
Dependent Claim

Claim 6
Dependent Claim
41 words
The connector of claim 1 in which said body is a rectangular tubular member having upper, lower, back and front walls and said keys are extensions of said tubular member, and said face plate extends above and below said tubular body.
Claim 7
Dependent Claim
43 words
The article of claim 1 further comprising a standard attached to said face plate, and a pair of cross-arms attached at each of the sides of said connector, said cross-arms having grooves into which said keys fit to reduce racking of said cross-arms.
Claim 8
