Columbia Throttle Tube - TZCTT

Built for professional drywall finishers, the ThrottleTube is designed to deliver joint compound to corners quickly, smoothly and with precise control. This tool features a  carbon fiber tube, providing superior strength and durability compared to traditional plastic tube designs while keeping the tool balanced and easy to handle.

A simple twist of the grip activates the internal piston, allowing compound to flow smoothly when needed and stopping instantly with a release of the twist for full control during application.

The white mud level indicator rod clearly shows the compound level. As the tube is filled, the rod extends outward, and when the red indicator becomes visible, it signals the tube is full. As compound is used, the rod gradually retracts back into the tube.

With its large compound capacity and extended reach, the ThrottleTube allows finishers to work longer with fewer refills, improving efficiency on the job.

Pair the ThrottleTube with Columbia Angleheads for fast, clean internal corner finishing, or use it with applicators to apply compound to inside and outside corners.
