    Abstract: A hardware kit for constructing a gate frame from standard board lumber includes a triple-junction bracket for joining three board members including a first horizontal board member and first and second equal length non-horizontal board members, and two mirror-image double-junction brackets each joining one of the non-horizontal members to a lower horizontal member of the frame. The triple-junction bracket has two attachment surfaces offset by 90 degrees, one of the surfaces having two attachment lengths diverging at an acute angle. Each double-junction bracket has a first attachment surface orthogonal to second and third attachment surfaces, the second attachment surface extending at an obtuse angle with respect to the third attachment surface, the obtuse angle exceeding 90 degrees by a number of degrees equal to half of the acute angle.
