WDCI Slide-on Connectors

These well-designed air tight connectors install quickly and easily to give your installation a clean professional look.

WDCI J & H Systems are also available in specialty metals. Consult distributor for minimum order, schedule and pricing.

Technical Data

The characteristics of a particular duct connection or joint are usually referenced to the Sheet Metal and Air Conditioning Contractors National Association (SMACNA) Manuals. SMACNA encourages the use of the new technology, but does not endorse proprietary products. The WDCI J & H Systems have been tested in accordance with SMACNA procedures with test results certified by Pittsburgh Testing Laboratory, Pittsburgh, PA. No external sealant was employed and the certified test results reveal: the WDCI J Systems are comparable to the SMACNA Class ‘J’ transverse joint and the WDCI H Systems are comparable to the SMACNA Class ‘H’ joint. Aluminum WDCI J is comparable to a SMACNA H connection. WDCI H is not available in aluminum or stainless.

Installation

Installation instructions are available in the Spec Data file for this product. Please refer to the Ductmate Library.

Limitations

The WDCI J System is not recommended for applications with duct gauges heavier than 16 GA or lighter than 26 GA.
The WDCI H System is not recommended for application with duct gauges heavier than 20 GA or lighter than 26 GA.

Composition and Materials

The WDCI Systems consist of the following components:
