Downspout connector consists of an attachment system for joining to open end of a downspout. The apparatus is hand-fastened to downspout without need of physical or permanent drain modification. The apparatus interface permits fluid movement through duct(s) to threaded hose connector. A conventional hose joins with threaded hose connector(s) for fluid distribution to remote locations. Downspout connector presents an easier, more efficient device for diverting and dispersing rainwater.

A unitary support assembly for connecting an air transport duct to a support includes a body portion, a duct connecting means integrally formed with the body portion for selectively securing the support assembly to the air transport duct, and a support connecting means integrally formed with the body portion opposite the duct connecting means for selectively securing the support assembly to the support.

A corner flange connection member configured for joining together adjacent duct channel flanges associated with duct sections includes two leg portions joined together in angular relationship by a corner portion, and at least one opening in said corner portion for receiving at least one fastening member for connecting said corner flange connection member to the duct sections. The at least one opening is shaped so as to threadably receive the fastening member without cutting threads.

A fastening member for joining together adjacent duct sections includes a head and a shank extending from the head, the shank having an unthreaded space adjacent to the head and a threaded portion extending from the unthreaded space, the threaded portion threadedly engaging a hole of an inserted corner plate positioned in flange of a first duct section. When the fastening member is fully inserted, the inserted corner plate positioned in the flange of the first duct section is retained within the unthreaded space.

In order to improve sealing performance when the open end of a tank is swaged and thereby secured inside an annular groove the surface of which is formed in a substantially rectangular shape with a seal material between the groove an the tank, flange parts protrude in a fan shape at the four corners of the seal material, and those flange parts are pressed by the corner sections of the annular groove, thereby preventing the seal material from moving in the corner sections.

A component for conducting a gas such as air, having a tubular main body and a connection element for connecting in a form-fitting manner to a further component, the connection element configured to be integral with the tubular main body, wherein the tubular main body and the connection element are configured from an elastic material, and wherein the connection element is configured to be formed by the tubular main body.

A fire-rated exhaust duct system comprising a modular configuration or structure. The fire-rated exhaust duct system comprises a plurality of exhaust duct sections. Each of the exhaust duct sections is configured to be joined or connected with other exhaust duct sections in the field or at an installation site, e.g. in building housing a kitchen facility or a laboratory facility to form longer sections or runs for exhaust duct system.

A device comprising an HVAC duct interconnector comprising a tube and a wall extending within the tube. The present disclosure at least partially addresses at least one of the above. However, the present disclosure can prove useful to other technical areas. Therefore, the claims should not be construed as necessarily limited to addressing any of the above. An example embodiment of the present disclosure provides a device comprising an HVAC duct interconnector comprising a tube and a wall extending within the tube.

A post clamp is disclosed as it may include one or more buffer components. In an example, each buffer component has a first shape on a post side and a second shape on a strap side. The post side is substantially flat and the strap side is substantially arc shaped. In an example, the post clamp also includes a fastener configured to strap the at least one buffer component against a post to secure the at least one buffer component to the post. In an example, the strap side of each of the buffer components has ridges forming a valley between the ridges. The fastener is configured to sit within the valley between the ridges so that the ridges maintain the fastener each of the buffer components and keep the fastener from slipping partially or fully off of the buffer components.
