Every 50.8mm (2 Inch) Dust Port Makita Miter Saw and the Right Vacuum Adapter
A 50.8mm dust port is a large port found on Makita's big miter saw. The number 50.8mm is the same as 2 inch. The port is round and measures 50.8mm across on the inside and 55mm on the outside.
A 2 inch port is wide for a reason. A 10 inch sliding miter saw makes a lot of dust fast. A bigger port moves more air, so more of that dust gets pulled away.
A GulpDust PETG adapter fits the 50.8mm saw port on one end and your vac hose on the other. No tape. No clamps. Below is the 50.8mm Makita miter saw we track.

The Adapter That Fits a 50.8mm Port
Each adapter grips the 50.8mm tool port on one end and steps it to your shop vac or dust extractor hose on the other end. Friction fit, no clamps. Made in the USA.
50.8mm (2 Inch) Dust Port Size: The Makita LS1019L Miter Saw Port
The 50.8mm port is round. It measures 50.8mm on the inside and 55mm on the outside. That inner number is the same as 2 inch.
Makita uses this large port on the LS1019L 10 inch dual bevel sliding miter saw. The port sits at the rear of the saw. A wider port like this moves more air than a small 38mm port, so it pulls dust harder.
A GulpDust adapter is printed to match the 50.8mm saw port on one end and your shop vac hose on the other end. A 2-1/2 inch shop vac hose is close to this size and pairs well, but the adapter seals the gap so no dust blows past.
How to Connect a Shop Vac to the Makita LS1019L
First, take off the factory dust bag. Look at the round 50.8mm port at the rear of the saw. Wipe out any dust so the adapter seats clean.
Press the adapter into the 50.8mm port. It is a friction fit, so it holds with a firm push. Then press your shop vac hose onto the other end.
Turn the vac on before you cut. A 10 inch slider throws fine dust with each pass. A strong vac at this wide port grabs much more of it than the bag does.
Why a 2 Inch Port Needs Good Airflow
A 2 inch port is built to move a lot of air. To use that, pair it with a shop vac that has strong airflow, not just a small detail vac.
Keep the hose short and straight when you can. Long, kinked hoses cut your suction. A short run from the saw to the vac keeps the dust moving fast through the 50.8mm port.

Yes. You can buy the printed PETG part shipped from the US, or download the STL file and print it at home. We suggest PETG with 3 walls and 25 percent infill.
