Magnum 4 Inch Flexible Coupler For Dust Collection Machine Ports (W1126)

Creates an air-tight, vibration-dampening bridge between 4-inch machine ports and rigid ductwork. The Magnum W1126 (KMS SKU: DC-W1126) uses a flexible rubber sleeve to compensate for slight alignment issues that would cause rigid plastic to crack. It is essential for high-vibration machinery like planers and jointers.

• Vibration Absorption - Rubber construction prevents machine hum from transferring through the entire duct system.
• Dual Worm-Gear Clamps - Provides everything needed to install the coupler right out of the box.
• Flexible Alignment - Allows for minor offsets between the machine and the stationary ducting drop.
