The Paramount J versus Hanging Strap
The J offers a fast installation, saving labor time and cost. Simply nail the hangers onto the joists approximately five feet apart, then place the duct into the saddle portion of the J. Strap often requires two installers who need to wrestle with flex, strap, cutters, and a nail/staple gun. This leads to excessive installation time and cost.
AIR FLOW QUALITY
Our smooth, 3" wide surface will support at least 2 of the helical wires inside the flex duct. This allows smooth and consistent air flow with no compression (sweat) of the insulation. Strap causes crimps in the flex duct, reducing air flow quality and insulation performance. This leads to complaints and expensive call backs.
BUILDERS / INSPECTORS
Industry professionals really appreciate a J hanger installation. They know it is a quality job that will eliminate homeowner issues. With the J hanger, the result is a better quality installation at a lower cost.
The J eliminates the expensive call backs caused by strap installations (air flow restriction due to crimping, sweat due to insulation compression, and corrosion / replacement).
Contractors who need access to a particular space can easily move the flex duct out of the J, then place it back into the J when finished. With strap, it is often cut down, requiring additional labor time and expense to re-hang.
The flexible material of the J allows it to bend to accommodate corners in the flex duct run. It can even be twisted completely down for easy use in crawl space applications. Straps will lead to excessive crimping and air flow problems in these situations.
The support rib along the underside of the J provides excellent weight bearing capability. This allows the J to be used for spiral pipe, metal pipe (including insulated), trunk lines in high velocity systems, and many contractors run their line set with the flex duct through the J hanger.
Our co-polymer plastic is heat, cold, and UV resistant. Strapping material often corrodes and requires replacement (call backs), and requires cutting lengths of strap which is time consuming and can cause injuries.
