SawStop JSS-120A60 Jobsite Saw Pro Dust Port Size and Vacuum Adapter Guide
The SawStop JSS-120A60 is the Jobsite Saw Pro. It gets hauled to work, so the mess follows you everywhere it goes. A table saw throws heavy chips and fine dust with every cut, and on a jobsite that means sweeping someone else's floor.
This saw has two dust ports, so know which one you are fitting. The main port is the round rear port: 2-1/4 in. (57.15 mm) inside and 2-9/16 in. (65 mm) outside, straight from SawStop's specs. There is also a smaller port on the blade guard, 1-3/8 in. inside and 1-11/16 in. outside. The adapter on this page fits the REAR port. A GulpDust PETG adapter matches that port on one end and your shop vac hose on the other end. No tape. No clamps.

SawStop JSS-120A60 Rear Dust Port Size: 2-1/4 in. Inside, 2-9/16 in. Outside
The rear dust port on the JSS-120A60 is round. The inside measures 57.15 mm, which is 2-1/4 in. The outside measures 65 mm, which is 2-9/16 in. SawStop lists both numbers on the product page, so you can order to them with confidence.
Most shop vac hoses are 1-7/8 inch or 2-1/2 inch. Neither one seals on this port by itself. A loose fit leaks air, and leaked air is suction you paid for and did not get.
A GulpDust adapter is printed in PETG to match the rear port on one end and your vac hose on the other end. The seal is snug, so the chips leave with the airflow instead of piling up under the saw.
Rear Port or Blade-Guard Port: Which One Is This?
The JSS-120A60 has a second, smaller port on the blade guard. SawStop lists it at 1-3/8 in. inside and 1-11/16 in. outside. It grabs the fine dust that comes off the top of the blade.
The rear port is the main line. It handles the heavy chips that fall inside the saw body. This page and this adapter are for the rear port. If you want to run both ports at once, measure the guard port too and use a wye fitting to join the lines.
How to Connect a Shop Vac to the SawStop JSS-120A60
First, clear packed chips out of the rear port. A jobsite saw eats framing lumber, and wet lumber packs the port fast.
Press the adapter onto the rear 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 start the cut, so the airflow is moving when the first chips fly.
SawStop JSS-120A60 Dust Collection FAQ
What size is the dust port on the SawStop JSS-120A60?+
The main rear port is round: 2-1/4 in. (57.15 mm) inside and 2-9/16 in. (65 mm) outside, per SawStop's specs. There is also a smaller blade-guard port at 1-3/8 in. inside. The adapter on this page fits the rear port.
Does the SawStop JSS-120A60 work with a regular shop vac?+
Yes, with the right adapter. A standard shop vac hose does not seal on the 57.15 mm rear port by itself. The GulpDust PETG adapter fits the saw port on one end and your vac hose on the other.
Should I hook up the rear port or the blade-guard port?+
Start with the rear port. It catches the heavy chips, which are most of the mess. The guard port grabs fine dust off the top of the blade. Running both is best, but the rear port alone makes the biggest difference.
Do I need clamps or tape to attach the adapter?+
No. The adapter is a friction fit. You push it onto the port and it holds. The same goes for the vac hose end.
Can I print this adapter myself?+
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.
