DW7331 Hood and Confirmed Dimensions
DEWALT confirms that the DW7331 hood mounts to the DW733 and DW734 planers. A separate support note gives two interfaces: the hood’s large opening measures 4 in. outside diameter, and the vacuum adapter opening measures 2.25 in. inside diameter.
| Interface | DEWALT dimension | What it means |
|---|---|---|
| Main hood outlet | 4" OD | Female fitting sized for a 4 in. outside diameter |
| Vacuum adapter | 2.25" ID | Measure the OD of the cuff that must insert |
Choose the Connection for Your Dust System
For a 4 in. duct or hose, start from the hood’s real 4 in. OD and verify that a female sleeve can fit over it without excessive play. For a shop vacuum, use the adapter supplied or intended for the hood, then compare its 2.25 in. ID with the actual OD of your cuff.
A hose sold as 2-1/2 in. may use a cuff with a different real diameter. The manufacturer’s 2.25 in. ID specification is therefore more useful than the hose’s trade size alone when deciding fit.
Measurements to Check Before Buying
- OD of the hood outlet or cuff that inserts into an adapter.
- ID of the sleeve or adapter receiving the part.
- Available insertion depth and any taper.
- Clearance around the hood and correct mounting on the planer.
Frequently Asked Questions
Does the DW7331 hood fit the DW734?
Yes. DEWALT support states that the DW7331 mounts to the DW733 and DW734.
What size is the large outlet?
DEWALT specifies a 4 in. outside diameter.
Will every 2-1/2 in. hose fit?
No. DEWALT gives 2.25 in. as the vacuum adapter’s inside diameter; compare your cuff’s actual OD with that value.

Disconnect the planer before installing or measuring the hood. Secure it with the specified hardware and never operate the machine with a loose dust-collection part.
