A connector includes a first member having a first bore, a second member having a second bore configured to align with the first bore, and a fastener for securing the first member to the second member through the first and second bores. The connector includes a tubular extension affixed to the first member and configured to encircle at least a portion of the first member and the second member. The tubular extension includes an access hole to permit insertion of the fastener through the first and second bores and an exit hole to permit extension of the fastener through the first bore or the second bore. The connector further includes a receptacle configured to slide over the tubular extension to form a weather-resistant barrier for the connector. The tubular extension is configured to support the receptacle.
