Abstract: The invention involves a T-post bracket allowing rapid and easy attachment of bracing T-posts to stanchion T-posts for fencing, trellis, or similar applications, and/or rapid and easy attachment of gates or other swinging structures to stanchion T-posts affixed to the bracket. The bracket has one end wherein a stanchion insertion space is provided between a stop member and a pair of retaining tabs, and insertion of a stanchion engagement fastener (e.g., a pin) engages the stanchion within the stanchion insertion space. Engagement legs may extend from the retaining tabs, and a bracing T-post may be fit between the engagement legs and pinned therein by insertion of brace engagement fasteners. Additionally or alternatively, a hinge post may extend from the bracket from a point about the stanchion insertion space, preferably from the stop member, to allow hanging of a gate or other swinging structure from the hinge post (and thus from a stanchion situated within the stanchion insertion space).
