Abstract: An improved cross-arm brace for supporting a cross-arm (24) on a utility support pole (23) is described. The brace has two support members (10) which lie along the support pole (23), one on each side of the support pole (23), and between the support pole (23) and the cross-arm (24). The support members (10) are connected to each other by one or more connecting members (11) which cross the pole (23) over that face of the pole (23) on which lies the cross-arm (24). Adjusting mechanisms (12, 14, 15, 16) associated with the connecting members (11) adjust to decrease the spacing between the support members (10) and thus to firmly wedge the support members (10) between the support pole (23) and the cross-arm (24). More than one cross-arm (24) on a support pole (23) can be supported by a single brace. The brace can be used in conjunction with a grid gain.
