POWERTEC 70357 4 Inch Wall Mounting Blast Gate with Bracket for Dust Collector, Dust Collection Fittings, 1 Pack
This wall-mount blast gate stands out for its space-efficient design, making it ideal for workshops with limited floor area. Compared with the POWERTEC 70326, which offers a more robust aluminum build, this model’s impact-resistant ABS plastic provides lightweight durability that’s easier to install and adjust. The integrated wall bracket ensures secure mounting, reducing the risk of accidental dislodging during operation. However, it requires regular cleaning to prevent dust buildup in the sliding groove, which could be inconvenient for busy workshops. Its sliding gate design ensures smooth airflow control, and the impact-resistant material withstands sawdust and woodchips effectively. Best for small workshops needing efficient wall-mounted dust management. Still, it may not be suitable for those requiring the most durable materials or frequent heavy-duty use.

Dust Right 2.5″ Ready-Mount Blast Gate for Woodworking Dust Collectors
This blast gate excels in preventing clogs through its self-cleaning design, which clears debris with each closure—ideal for maintaining high airflow. Unlike the POWERTEC 70326, which uses aluminum, this model’s reinforced polymer body offers long-term durability without adding weight. Its integral mounting bracket simplifies wall installation, making it perfect for DIY setups or small workshops.

Constructed from durable black ABS plastic, they resist abrasion from sawdust and chips. The gates are designed to fit most 2-1/2-inch ID hoses and ports, similar to the single POWERTEC 70357 model but in a cost-effective bundle. Although the compatibility requires confirmation of port sizes, the included units deliver good airflow regulation at a budget-friendly price. They’re easy to install, with the same straightforward sliding gate operation as higher-end models. The primary tradeoff is that these are not metal, so they may not withstand the most rigorous industrial environments. Best for hobbyists or small shops needing multiple gates without breaking the bank. Not ideal for high-impact or industrial applications.
Pros:- Cost-effective 2-pack bundle
- Made from durable ABS plastic
