منفذ غبار السياج 2-1/2" من Infinity Tools

My drill press fence was a total sawdust factory until I installed this port—the 2-1/2" ID fits my shop vac hose perfectly and the 6-3/4" length gave me plenty of room to mount it securely.

Mounted this on my shop-built router table fence and it fits my 2-1/2" hose perfectly. The 2-3/4" outer diameter seated cleanly in the hole I drilled, no wobble or tape needed. Cut my cleanup time on MDF routing down to almost nothing.

Installed this on my router fence and it fit the 2-1/2" hose perfectly, no adapters needed. The plastic seems sturdy enough for shop use. Just wish the mounting screws were included.
