## 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 “screwed”. 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.
