Abstract: A frame for bracing a gate includes a first and second upright brace having respective outboard edges positioned flush to opposite vertical edges of the gate. First upper and lower cross braces have respective opposite ends received within upper and lower ends of the first and second upright braces. Second upper and lower cross braces respectively have opposite ends abutting upper and lower ends of the first and second upright braces. First and second upper mounting members respectively have outboard ends abutting upper ends of the first and second upright brace member and inboard ends secured to the first and second upper cross braces. First and second lower mounting members respectively have bases abutting lower ends of the first and second upright braces and inboard ends secured to the first and second bottom cross braces. The structure enables mounting of a gate on a non-level surface.
