## Description

CLAMP TOGETHER DUCTING: Cut-Offs or Blast Gates ** This item is compatible with Quick-fit Ducting (QF Duct), K&B Duct, and US Duct. CONSTRUCTION: The standard FULL cut off / blast gate is an aluminum cast housing to which collars have been &#x201C;screwed&#x201D;. The screw is then ground off on the inside to keep it out of the air stream. Application: Cut offs or Blast Gates are used primarily to cut off air supply to areas when dust collection/venting is not needed. This can improve performance in other areas or simply limit the size of the needed collector.

## Features

- Energy Saving
