Air travelling throughout a duct is slowed up when it reaches a right turn angle. This "slow-up" is detrimental to the efficiency of the duct system, therefore air turning vane assemblies are used to guide air evenly around such turns. With today's high labor costs, it is expensive for shops to produce their own air turning assemblies. That is why Duro Dyne Vane Rail is a major contribution to sheet metal shops that require efficient, yet inexpensive air turning assemblies.

The sensible solution to making your Flexible Duct Connector Seam!

Follow these simple steps to join your flexible duct connector together. FCA Flexible Connector Adhesive

1. Cut away 1 1/2" of metal from one side of your connector, leaving a 1 1/2" tongue of fabric. (Fig. 1)

2. Overlap connector ends 1 1/2" and screw or weld together. (Fig. 2)

3. Apply one or two lines of FCA, sparingly, on fabric, under tongue.

4. Press tongue down on adhesive. Rub gently and hold for 10 seconds. (Fig. 3)

5. For an airtight connection, apply duct sealer over metal joint.

How to Stifen Flexible Conector

When installing large size flexible connectors in a duct system, some type of stiffening agent is usually required to keep the unit relatively rigid. Some contractors use angle iron, while in many cases a bar slip connection is used to achieve this result. Now it is possible to save valuable time and material by forming Duro Dyne's Grip Loc Seam found on Metal Fab and Super Metal Fab, to rigidize the connector over long sections. This simple method of stiffening the sides of Duro Dyne Flexible Connector can eliminate the costly addition of angle iron used to perform this job. Here is how it is done:
