Aspects of the disclosure are directed to brackets, their manufacture and use, such as may involve securing siding and/or other building materials. As may be implemented in accordance with one or more embodiments, an apparatus includes a front side, a back side, and a top side connecting the front side and the back side, the front, back and top sides (e.g., as a bracket) forming boundaries that bound three sides of an opening. A grip fastener is coupled to the front side and extends inward toward the opening and toward both the back and top sides at an incline relative to the front side. Another grip fastener is coupled to the back side and extends inward toward the opening and both the top and front sides at an incline relative to the back side.
