Choose the CNS175-PFA30 when your recurring finished rip width is 30 inches or less and the shorter package fits the shop. Move to the CNS175-TGP236 only when you genuinely need up to 36.5 inches to the right of the blade. Choose the CNS175-TGP252 only for recurring work above that limit and up to 52.5 inches.

The important finding is what does not change. SawStop’s current U.S. pages list the same 1.75 hp CNS175 motor, 225-pound saw body, 25.75-by-27-inch body footprint, 3-1/8-inch square cut depth, and 2-1/4-inch 45-degree cut depth across all three packages. The wider options buy fence and table envelope, not a deeper cut or a different motor.

That makes this a rip-width and workspace decision. The old ToolForge reviews treated the Contractor Saw as one fixed machine and made broad claims about mobility, dust, upkeep, and used examples that the retained evidence could not support. This replacement keeps the exact package code and measurable stop rules in view.

Exact package Fence and documented rip Listed assembled envelope Listed assembled weight Best evidence-backed fit
CNS175-PFA30 30-inch Premium; 30 in right, 12 in left 61.75 x 40.5 x 34.75 in 256 lb Recurring rips stay at or below 30 in and the shortest package matters
CNS175-TGP236 36-inch T-Glide; 36.5 in right, 12.5 in left 69.125 x 45 x 34.75 in 310 lb A real 30-to-36.5-in rip requirement justifies the added envelope
CNS175-TGP252 52-inch T-Glide; 52.5 in right, 12.5 in left 85.25 x 45 x 34.75 in 335 lb Recurring rips above 36.5 in justify an 85.25-in-wide machine

All three source pages list two stamped-steel extension wings, a miter gauge, Micro Blade Guard, riving knife, push stick, 10-inch blade, standard insert, and standard brake cartridge. Optional cast-iron wings are not included in these rows.

The dimensions above describe the assembled machine, not the working shop. They exclude stock length, operator position, infeed, outfeed, hose routing, and access around the controls.

Treat the full package code as the product identity

“CNS175” identifies the shared saw, but it does not identify the fence, rails, extension table, assembled width, or total package weight. Those differences sit in the suffix. A listing described only as a “SawStop Contractor Saw” therefore leaves the main buying decision unresolved.

Match the complete code on the listing and paperwork to PFA30, TGP236, or TGP252, then compare the included parts with the corresponding current package page. This matters most with open-box and used machines, where a seller may photograph the saw body closely but omit the full rails, table, guard, or fence hardware from the frame.

Do not infer one package from the visual length of a rail in a cropped photograph. Ask for the full package code and an inventory of the included components. If the code, fence, rails, and table do not resolve to one current configuration, price and plan it as an incomplete or mixed package until SawStop confirms compatibility. The exact Amazon routes later in this review are searches for that same reason: the model suffix must survive the trip from comparison to checkout.

What the wider packages actually change

From 30 inches to 36 inches

The TGP236 adds 6.5 inches of documented right-side rip over PFA30. It also adds 7.375 inches of overall width, 4.5 inches of depth, and 54 pounds. Its extension table is listed at 23.75 inches wide instead of 12 inches.

That is a poor trade if the extra rip band is only hypothetical. It is a sound trade when a repeated project dimension sits between 30 and 36.5 inches and the full stock path fits.

From 36 inches to 52 inches

The TGP252 adds 16 inches of documented right rip over TGP236. Listed depth stays at 45 inches, while overall width rises by 16.125 inches and assembled weight by 25 pounds. The extension table grows from 23.75 to 40.125 inches wide.

Do not buy this package because 52 sounds future-proof. Buy it because a named recurring cut fails the 36.5-inch gate and the 85.25-inch assembled width still leaves a controlled feed path.

The floor rectangle is only a warning light

Multiplying SawStop’s listed width and depth gives approximate machine rectangles of 17.37 square feet for PFA30, 21.60 for TGP236, and 26.64 for TGP252. Those calculations make the package growth visible, but they are not installation requirements.

OSHA’s table-saw guidance says to leave sufficient clearance and support all pieces of stock, including cut and uncut ends. A wide fence number does not create the room to control a long panel before, during, and after the blade.

Four gates before choosing a package

1. Name the recurring rip width

Measure the finished distance from the blade to the right side of the fence for the jobs you actually repeat. Use the smallest current package that passes that dimension. This preserves shop space without pretending a smaller capacity can do the larger job.

The listed left-side rip also differs: 12 inches on PFA30 and 12.5 inches on the two T-Glide packages. Do not swap a right-side capacity into a left-side setup.

2. Draw the deployed stock path

Plot the machine envelope, operator position, infeed length, outfeed length, and support surfaces. Add the dust hose and the route to the power switch. If the saw shares a garage with storage or a car, draw both the working and parked states.

Our table-saw buying guide for beginners explains why rip capacity and stock support are separate checks. If the real decision is still table saw versus another machine class, use the four-model miter-saw versus table-saw map before choosing a CNS package.

3. Resolve mobility and accessories together

The word “contractor” does not make a 256-to-335-pound assembled package portable. SawStop’s current Contractor Mobile Base manual requires the stand to be fully assembled before the base is installed. A base changes positioning; it does not remove mass or working-clearance requirements.

Use the current SawStop configurator after choosing the fence. It displays compatibility warnings as accessories are combined. Do not assume a mobile base, inline router table, dust accessory, wing, or fence route fits merely because each item is sold for part of the CNS family.

4. Keep the safeguard package complete

The contact-response brake is one control, not the entire safety plan. Every sampled package also includes a guard, riving knife, and push stick. OSHA separately identifies guarding, a spreader function, push-stick use, anti-kickback measures, correct blade selection, stock support, and operator position as material controls.

Reject a new or used listing until the exact guard, riving knife, push stick, cartridge, insert, fence code, and matching manual are resolved. Do not replace an evidence gap with a seller’s broad statement that the saw is complete.

Blade and dado boundaries matter before checkout

The three package pages list a 10-inch blade and the same cut depth. SawStop’s product guidance says the standard system is designed for standard 10-inch blades within its stated kerf range. For an 8-inch dado stack up to 29/32 inch, it requires the separate dado cartridge and insert and lists additional blade-construction restrictions.

That means “supports dado cuts” is not a complete buying answer. Verify the exact stack, cartridge, insert, and current manual before treating the operation as available. This article is a purchase map, not operating instruction.

The old local reviews also implied that every brake activation automatically destroys the blade and machine. SawStop’s current product guidance is narrower: replace the cartridge, evaluate the blade for future use, and follow the documented recovery path. We do not have independent activation testing and do not turn that guidance into a durability claim.

Who should buy each version?

Choose CNS175-PFA30 when

  • repeated finished rips stay at or below 30 inches;
  • 61.75 by 40.5 inches is the only sampled machine rectangle that fits comfortably;
  • you do not need the T-Glide table extension for a named task; and
  • the exact accessory combination passes the current configurator.

The CNS175-PFA30 Amazon route is an honestly labelled exact-model search, not a verified direct product page. Confirm the package code and included parts before ordering.

Choose CNS175-TGP236 when

  • a recurring rip falls above 30 and at or below 36.5 inches;
  • the 69.125-by-45-inch envelope and 310-pound assembled package fit;
  • the wider extension table has a defined role; and
  • you have measured the complete stock-support route.

The CNS175-TGP236 search is also a search fallback rather than a direct ASIN.

Choose CNS175-TGP252 when

  • a recurring rip falls above 36.5 and at or below 52.5 inches;
  • the 85.25-inch machine width is deliberate;
  • long stock can remain supported through the whole cut; and
  • the added table does not block the operator, dust, access, or accessory plan.

The CNS175-TGP252 search requires the same identity check.

If the CNS fails because it must travel regularly, inspect the separate SawStop Jobsite Saw Pro review . If it fails because a permanent shop needs a different cabinet, power, or dust architecture, start with the SawStop Professional Cabinet Saw review . Those are different machine decisions, not automatic upgrades.

Method and limits

This is a current configuration and safeguard audit, not a hands-on test. We retained six sources: three current SawStop U.S. package pages, the current contractor-saw configurator, the Contractor Mobile Base manual, and OSHA table-saw guidance. We normalized exact identity, fence, right and left rip, overall envelope, assembled weight, extension table, shared motor and body, cut depth, included safeguards, mobility sequence, and public safety boundaries.

We did not test cut quality, alignment, stability, dust capture, mobility, vibration, noise, durability, brake activation, assembly, or transport. The table covers three standard U.S. packages, not every configurator permutation or international version. Calculated square-foot figures compare listed machine rectangles only. Manufacturer claims remain attributed, and OSHA guidance is not a consumer ranking or a complete operating procedure.

No current price, stock, discount, rating, review count, ownership, customer consensus, resale, or direct ASIN is claimed. The useful result is narrower and reproducible: choose the smallest exact package that passes the recurring rip, deployed-space, accessory, and safeguard gates.
