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.
