A saddle for an insulating support bracket includes an arcuate central portion defining a first end and a second end opposite the first end, at least one vent formed through the arcuate central portion; a first flange portion bent radially inward from the arcuate central portion at the first end, a first fastener hole formed through the first flange portion, wherein the first fastener hole is accessible through the at least one vent; and a second flange portion bend radially inward from the arcuate central portion at the second end, a second fastener hole formed through the second flange portion, wherein the second fastener hole is accessible through the at least one vent.

An antenna assembly and related methods are described. The antenna assembly (1) comprises an extendible mast (2) constructed and arranged so as to be configurable between a coiled form and an extended form. The extended mast (2) is resiliently biased in the form of an elongate tube having a slit along its length. The coiled mast is wound about an axis extending transversely to the longitudinal extent of the mast. An antenna (6) is integrally coupled to the mast such that when extended, the mast supports and positions the antenna, and when coiled, the mast and antenna are coiled together.

The present invention relates to a novel plumbing drain cable device. The drain cable device is a device for cleaning a plumbing drain blockage. The device is comprised of a flexible stainless steel corrugated tube with a nut on one end to allow connections for multiple extensions to lengthen the tube, as needed. The device has a rubber coating on the outside to help assist with grip and is cut at a 45-degree angle with rubber coating wrapped around the inside edge of the cutout to protect a user from cuts. Users would bend the tube in the direction of a drain fitting. A snake machine cable will travel through the tube of the device and up the direction of the drain to the clogged area. Thus, the device helps guide rotor machine cables through a one way clean out without getting the cable kinked and/or stuck.

The blowable flexible innerduct contains an outer innerduct structure and an inner innerduct structure. The outer innerduct structure contains at least one outer longitudinal chamber formed from at least one textile. The inner innerduct structure contains at least one inner longitudinal chamber, where each inner longitudinal chamber is located within an outer innerduct textile chamber and the at least one inner longitudinal chamber contains an inflatable tube. The inflatable tube has a wall thickness of less than about 0.5 mm. The inner longitudinal chamber alone has an air permeability of less than about 1 cfm, outer longitudinal textile chamber alone has an air permeability of greater than about 100 cfm, and the outer and inner longitudinal textile chambers together have an air permeability of less than about 1 cfm.

A system for packing and assembling a flexible duct that includes a sleeve. The sleeve includes a tubular vapor barrier and an insulating layer within the vapor barrier and includes a central cavity. Further, the sleeve is radially compressed and rolled along an axial direction. The system also includes an air core sized to fit within the central cavity of the insulating layer. The air core includes a sheet that blocks fluid flow therethrough and a structural support coiled within the sheet and the air core is flattenable and not within the rolled sleeve.
