Large Router Plate Buyer Guide
Large Router Plate Buyer Guide
Modulus Arms has been a leader in 80 lower jig development and router-based tooling since 2014.
The Large Router Plate is an optional Modulus adapter for Router Jig Extreme that allows certain full-size and two-handle routers to work with the jig system. It is not for standard trim routers. Buyers searching large router plate, large router base, or full size router 80 lower jig usually need to know whether their router requires this plate before buying SpeedMill or a tool kit.
Quick answer: if Modulus product documentation assigns your router to Version 4 or premium 4D SpeedMill, or if you are using a listed full-size or two-handle router, check the Large Router Plate page before checkout.
What the Large Router Plate Is
Modulus describes the Router Jig Extreme Large Router Plate as an optional 6061 billet aluminum plate used to attach a large router for 80 lower jig work with Router Jig Extreme. The product page states it allows full-size routers to be used with the jig system.
Important buyer language from the page:
- Optional adapter plate
- 6061 billet aluminum construction
- For full-size routers or routers with two handles
- Not compatible with standard trim routers
That last point should appear early in the article because it eliminates a common wrong purchase path.

When Buyers Need a Large Router Plate
Buyers usually arrive at this topic from one of three paths:
| Entry path | Typical question |
|---|---|
| SpeedMill Version 4 / 4D | Does my router need extra hardware? |
| Full-size router ownership | Can I use my existing large router with Router Jig Extreme? |
| Tool kit purchase | Should I add the plate during initial tooling purchase? |
Modulus product pages link Version 4 and D/4 SpeedMill paths to the Large Router Plate requirement. The premium tool kit page also advises that routers needing D/4 SpeedMill may need the Large Router Base or Large Router Plate.
All three paths lead to the same answer: verify router form factor and product-page requirements before ordering.
Listed Full-Size Router Examples
The Large Router Plate product page lists these routers as suggested to work without issues:
- Craftsman 2767
- Craftsman 27683
- Craftsman 50429
- DeWalt DW616
- Hitachi M12VC
- Porter Cable 8902
- SKIL RT1312-00
Use this list as product-page examples, not as a promise that every variant or revision will fit forever. The live product page and compatibility chart remain the source of truth before ordering.
If a router is not listed, the safe support message is to contact Modulus or verify current documentation rather than assuming compatibility.
Trim Router vs Full-Size Router
This distinction is central to the buyer guide:
| Router type | Large Router Plate relevance |
|---|---|
| Standard trim router | Not compatible with Large Router Plate product intent |
| Compact router on listed chart | May work through SpeedMill version matching without plate |
| Full-size router | May require Large Router Plate |
| Two-handle router | Explicitly mentioned as supported use case on product page |
Modulus tool-kit category copy reinforces that some buyers need a large router plate adapter when using a preexisting large router. That makes this topic more than accessory merchandising—it is a compatibility requirement for part of the router market.
How the Plate Fits the Modulus Product Ecosystem
The Large Router Plate is one node in a support cluster:
- Router Jig Extreme SpeedMill
- Router Jig Extreme Tool Kit with SpeedMill
- Router Jig Extreme Premium Tool Kit with SpeedCoat
- Replacement 5/16 inch End Mill
Buyers researching the plate often still need SpeedMill sizing and replacement end mill paths. The links below cover that ecosystem.

Buyer Checklist Before Buying the Large Router Plate
- Are you using Router Jig Extreme?
- Is your router a standard trim router? If yes, this plate is not the right product.
- Is your router full-size or two-handle?
- Is your router listed on the Large Router Plate product page?
- Does your SpeedMill path show Version 4 or premium 4D?
- Have you already selected the correct SpeedMill or tool kit version?
- Do you also need replacement end mills or premium coated replacements?
This checklist helps the page rank for support queries and reduces wrong orders.
Common Buyer Mistakes
| Mistake | Result | Better approach |
|---|---|---|
| Buying plate for trim router | Product mismatch | Confirm router form factor first |
| Selecting Version 4 SpeedMill without plate | Incomplete setup | Add plate when product page requires it |
| Assuming all DeWalt routers fit | Model-specific fitment varies | Match exact model to chart |
| Treating plate as universal jig accessory | Product is Router Jig Extreme-specific | Verify jig family first |
| Ignoring replacement tooling path | Long-term support gap | Plan end mill replacements upfront |
Price and Bundle Context
The Large Router Plate is an accessory purchase that may follow—or accompany—a SpeedMill or tool kit decision. Current product-page examples in the Modulus catalog include:
- Large Router Plate listed at $39.99
- SpeedMill listed at $65.99
- Router Jig Extreme Tool Kit with SpeedMill listed at $77.97
- Premium Tool Kit with SpeedCoat listed at $104.38
Prices and stock status can change, so live product pages are authoritative. The plate is a relatively low-cost compatibility accessory compared with buying the wrong router path or replacing damaged tooling later.
