2-1/4 in. (57.15mm) Dust Port Tools and Shop Vac Adapter Guide for Table Saws and Planers
A 2-1/4 in. (57.15mm) port is the large port you find on jobsite table saws, cabinet saws, and benchtop planers. The port is round and about 57 to 58mm across on the inside. On the outside it runs close to 63.5mm, which is why a 2-1/2 in. shop vac hose often looks like it should fit but sits loose.
These are shop tools that make a lot of chips fast. A loose hose dumps that dust on the floor and in the air. A sized PETG adapter grips the tool port on one end and steps it to your shop vac or dust collector hose on the other end, so the airflow stays sealed.
Below is every table saw and planer with a verified 2-1/4 in. dust port that we track. Each one shows the verified inner and outer size and the source we cite. Tool detail pages are being built, so these are listed as text for now.

The Adapter That Fits a 2-1/4 in. Port
Each adapter grips the 2-1/4 in. 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.
What 2-1/4 in. (57.15mm) Means on a Table Saw or Planer Port
A 2-1/4 in. port measures about 57 to 58mm across on the inside. On the outside it runs close to 63.5mm. The port is round and molded into the back of the saw or planer. It is meant to pull the heavy chip stream a table saw or planer throws.
The DeWalt DWE7491RS and DCS7485T2 both verify at 58.4mm inside. The Bosch GTS1041A, Ridgid R4518, and SawStop JSS verify at about 57.15mm inside. The Triton TSPL152 planer verifies at 58mm inside. That whole spread sits inside the PETG friction-fit clearance, so one adapter sized for this family seats in all of them.
Do not trust the label alone. A 2-1/2 in. shop vac hose is close in size but not the same. The hose can slip on and still leak because the fit is loose. Match the adapter to the verified port size, not to the number on the box.
Why a 2-1/2 in. Shop Vac Hose Leaks on a 2-1/4 in. Port
Most shop vac hoses in the US are 2-1/2 in. That number is the hose size, not the tool port size. The tool port is a touch smaller inside, so a bare hose end wobbles and breaks the seal.
A sized adapter fixes both ends at once. One end grips the 2-1/4 in. tool port with a friction fit. The other end steps to your 2-1/2 in. hose or your dust collector. No tape, no clamps, no gaps.
How to Confirm Your Saw or Planer Before You Buy
If your exact model is in the list above, the verified size is shown next to it. If your model is not listed, measure the port with calipers. Close the jaws around the outside of the port stub for the outer size, and inside the opening for the inner size.
Round to the nearest standard size if your number falls between two. A port that measures 57 to 58mm inside is in this 2-1/4 in. family. A port near 63.5mm inside belongs on the 2-1/2 in. page instead.
2-1/4 in. Dust Port FAQ
Which table saws really use the 2-1/4 in. (57.15mm) port?+
Verified saws in this family are the DeWalt DWE7491RS and DCS7485T2 (both 58.4mm inside), the Bosch GTS1041A REAXX and Ridgid R4518 (both about 57.15mm inside), and the SawStop Compact Table Saw and Jobsite Saw Pro (58 and 57.15mm inside). The Triton TSPL152 planer shares the same family at 58mm inside. Each verified size traces to a real adapter or manufacturer source in our verification file.
Will one adapter fit all of these saws?+
Yes. Every port in this family verifies between 57 and 58.4mm inside. That whole range sits inside the PETG friction-fit clearance, so an adapter sized for the 2-1/4 in. family grips all of them. The other end is what you choose to match your shop vac or dust collector.
My saw port says 2-1/2 in. Is that this size?+
Maybe not. Many table saw ports are about 2-1/4 in. inside and about 2-1/2 in. outside. The outside number is often what gets printed. Measure the inside of the port. If it is 57 to 58mm, this is your page. If it is near 63.5mm inside, use the 2-1/2 in. page.
Can I use a regular shop vac with a table saw?+
Yes, with the right adapter. A shop vac moves less air than a big dust collector, but for a jobsite saw it works fine. The GulpDust PETG adapter grips the 2-1/4 in. saw port and steps it to your shop vac hose so the dust goes into the vac, not the air.
Can I print this adapter myself?+
Yes. You can buy the printed PETG part shipped from the US, or download the STL and print it at home. For a large port like this we suggest PETG with 3 walls and 25 percent infill.
