Straight Adapters

Duct-to-Duct

Duct-to-Duct with Flange

Duct-to-Hose

Adapters join quick-disconnect duct to other duct systems. Duct-to-duct adapters connect to standard and spiral duct. Duct-to-duct with flange adapters provide a secure connection between duct. Duct flanges are also available. Duct-to-hose adapters are slightly undersized. Slide hose over the adapter and hold it in place with a hose clamp (not included).

Blast Gates

Plastic Gate Material

Control the flow of air and material through duct systems.

ABS plastic gates work with plastic duct and duct hose. They withstand impact and abrasion. Gates with a stay-put slide do not require a locking screw.

Design-Your-Own Dust Collector Duct System

Use these components (sold separately) to put together a duct system to collect sawdust, chips, shavings, and granular material from woodworking operations. Hose clamps are available.

For maximum safety and to avoid a dangerous buildup of static electricity, you must use the grounding kit (sold separately).

If you need more information on designing and installing a dust collection system, order our book "Dust Collection Basics."

Connectors

Style E is also known as a quick-disconnect duct fitting and is used in place of a hose clamp. Attach to the end of a 4" dia. hose and then press on to any dust hood for a quick and easy friction fit.
