Ripping dimensional lumber, sheet goods, or shelving boards with a handheld saw often requires maintaining a consistent parallel cut along an existing straight edge. While setting up clamp guides or positioning standalone straightedges can stabilize cuts, attaching a dedicated edge guide directly to the tool provides rapid, repeatable guidance on job sites and in home workshops. Selecting the right dewalt circular saw rip fence requires matching the mounting bracket geometry, slot width, and saw shoe dimensions to your specific tool body.
Within the available catalog of rip guides built for this platform, options are organized primarily by saw frame size, shoe casting, and manufacturer origin. The range divides into fences built to the DW3278 specification for full-sized 7-1/4-inch and 8-1/4-inch framing saws, brackets designed around the 381091-00 standard for 6-1/2-inch cordless trim saws, and specialized accessories like the N633323 for compact barrel-grip tools. Shoppers also weigh factory OEM components against third-party direct-fit replacements that supply replacement mounting hardware.

The DW3278 Rip Fence for Dwalt Circular is an all-metal guide designed by Aitruman to fit full-sized corded and cordless framing saws. It matches the factory DW3278 profile, allowing it to slide into the front shoe casting channels on saws ranging from 7-1/4 inches to 8-1/4 inches. The listing confirms compatibility with high-demand heavy-duty tools, including the corded DWE575 and DWE575SB, the DWS535 worm-drive style framing saw, classic units like the DWE364 and DW384, and high-powered cordless framing options. Those running high-draw platforms like dewalt 60v tools such as the DCS575 or DCS577 can use this fence to establish straight parallel cuts along framing stock.
Installation follows the standard mechanical design used across the brand’s larger circular saws. The user slides the fence arms through the dedicated slots on the front of the saw shoe and tightens the included round head stop screw against the tension spring. The listing indicates the item weighs 4.54 grams, pointing to an ultra-lightweight profile, though exact ruler graduations on the guide arm are not specified.
This replacement model suits general contractors and woodworkers needing a simple, direct-replacement dewalt circular saw rip fence for primary framing saws. It gives way to smaller models when using compact trim saws, as its bracket arm spacing is too wide for 6-1/2-inch saw bases.

Manufactured by uhzz, the DW3278 Circular Saw Rip Fence Compatible is a direct replacement edge guide built for large-format saws. The manufacturer notes construction from wear-resistant raw materials subjected to strict testing to withstand repeated jobsite adjustments. The listing indicates compatibility with major 7-1/4-inch tools, serving as a dedicated dewalt DCS570 rip fence option as well as fitting the DCS575, DCS577, DWE575, DWE575SB, DWE364, DWS535, and DW384.
The guide locks securely across the front of the saw shoe to provide rigidity during long rip cuts in plywood or dimensional stock.

Cons
- Mounting hardware not specified

The DeWalt OEM N633323 Circular Saw Rip is a genuine factory-manufactured edge guide made specifically for the brand’s compact cordless trim saws. Carrying official part number N633323, this OEM component is designed explicitly for the DCS571 series, covering both the bare-tool DCS571B and the kitted DCS571P1. Because compact saws utilize a distinctly narrower frame, smaller baseplate, and 4-1/2-inch blade diameter, standard framing guides are entirely incompatible.
This dewalt DCS571 rip fence provides factory-standard tolerances for users operating a dewalt compact circular saw in tight quarters, such as ripping thin flooring planks, overhead paneling, or narrow trim pieces. The listing emphasizes its genuine OEM status, guaranteeing an exact fit into the DCS571 shoe without binding or loose play.
The listing does not specify whether mounting screws, tension springs, or dimensional markings are included in the package. This model is intended exclusively for owners of DCS571 compact saws; it cannot be mounted to standard 6-1/2-inch or 7-1/4-inch circular saws.

The guides slide into the front shoe bracket slots to maintain consistent spacing from the saw blade across the entire width of the cut.

The listing verifies broad support across legacy and modern platforms, including the DC390K, DW936, DW936K, DC300, DC310, DCS391B, DCS393, and DC390B.
Engineered to assist with repetitive ripping tasks, this circular saw rip guide for dewalt saws slots directly into the guide receiver on the cordless saw base. The kit includes a round head stop screw and spring, allowing quick mounting without sourcing separate hardware. The listing indicates an overall product weight of 2.29 ounces, making it a lightweight addition that preserves the balance of cordless tools. While a track system like a dewalt cordless track saw handles wide sheet goods across long distances, this edge guide offers rapid setup for narrow board ripping directly from the saw shoe.
This guide is best suited for owners of 6-1/2-inch cordless saws who prioritize high speed steel durability for daily jobsite trim cuts. It gives way to DW3278-style guides when operating 7-1/4-inch tools.
Matching a Model to Your Setup
- For ripping dimensional lumber and framing plates using standard 7-1/4-inch corded tools like the DWE575 or cordless DCS570, choose the DW3278 Rip Fence for Dwalt Circular.
- For trim carpentry, subfloor trimming, and sheet cuts using a 6-1/2-inch cordless saw like the DCS391B or DCS393, select the 381091-00 Circular Saw Rip Fence.

- For making narrow rip cuts in tight quarters with a 4-1/2-inch DCS571 compact cordless saw, use the DeWalt OEM N633323 Circular Saw Rip.
- For outfitting multiple framing saws across a crew or keeping a spare guide in the shop truck, pick the two-pack DW3278 Circular Saw Rip Fence.

Before You Buy
Before purchasing an edge guide, verify the exact mounting slot dimensions and guide spacing on your circular saw shoe. Saws across different frame categories—such as 4-1/2-inch compact models, 6-1/2-inch trim tools, and 7-1/4-inch framing saws—utilize distinct bracket widths that cannot be interchanged. While third-party listings specify compatibility lists, they rarely detail the maximum rip width capacity, leaving users to confirm whether the extension arm length accommodates their desired cut dimensions.
Additionally, review the hardware specifications included with each listing. Most compatible models supply a standard round head stop screw and tension spring, but listings do not specify screw thread pitches or whether they match older casting revisions. For genuine components like the N633323, the listing does not specify whether mounting screws are included, which may require repurposing existing factory hardware or sourcing an appropriate fastener separately.
FAQ
Which dewalt rip fence fits my saw?
The correct fence depends on your saw model and blade size. Full-sized 7-1/4-inch and 8-1/4-inch saws such as the DWE575, DCS570, and DWS535 require a DW3278-pattern fence. Cordless 6-1/2-inch models like the DCS391 and DW936 require a 381091-00 guide. Compact 4-1/2-inch saws, specifically the DCS571, require the dedicated N633323 guide.
How do you install a circular saw rip guide for dewalt?
To install the guide, slide the rail arms through the open slots located at the front of the saw shoe. Thread the included stop screw and tension spring into the designated mounting hole on the shoe casting, adjust the fence face to the desired cut width using the guide scale or a tape measure, and tighten the screw firmly to lock it in place.
Can a DW3278 rip fence fit on a 6-1/2-inch cordless circular saw?
No, a DW3278 rip fence cannot fit a 6-1/2-inch saw. The arm spacing on the DW3278 is engineered for the wider shoe castings of 7-1/4-inch and 8-1/4-inch saws. Saws with 6-1/2-inch blades require the narrower 381091-00 rip fence.
What is the difference between OEM DeWalt fences and third-party compatible models?
OEM fences are produced directly by the original tool manufacturer to match factory specifications. Third-party compatible fences are manufactured by aftermarket brands to mirror original dimensions, often bundling replacement screws and springs or offering multi-pack configurations.
Does the DeWalt OEM N633323 rip fence fit full-sized circular saws?
No, the N633323 rip fence is designed exclusively for the DCS571 compact 4-1/2-inch circular saw. It features narrower mounting geometry tailored to the compact chassis and cannot bridge the wider baseplate slots of full-sized framing saws.
