The Carlson Extra Tall Walk Through Pet Gate is worth considering if you want a 36-inch steel gate for an indoor doorway and a separate flap for a smaller pet. The white 0941 model fits 29–31 inches without the extension or 34–36.5 inches with the included 4-inch extension. A 32- or 33-inch doorway falls between those two configurations.
Which doorway widths fit the Carlson 0941?
| Clear opening | White 0941 setup | Buying decision |
|---|---|---|
| 29–31 in. | Standard frame | Use the gate without the included extension. |
| Over 31 and under 34 in. | Outside the listed fit ranges | Choose a model whose specified range covers your opening. |
| 34–36.5 in. | Frame with the included 4-in. extension | Check that the retailer listing includes the extension and mounting hardware. |
| Under 29 or over 36.5 in. | Outside the listed fit ranges | Choose a gate rated for your opening. |
Measure between the surfaces where the hardware will sit, once low and once higher up. Baseboards and trim can change the clearance. If the top and bottom readings differ or the mounting surfaces are uneven, check the manual before ordering. For other openings, see our wide pet gate buying guide.

Amazon vs Walmart for the same white 0941
| Retailer | Listing to look for | What to check before ordering |
|---|---|---|
| Amazon | ASIN B000JJFNJK, white 36-inch Carlson gate | Confirm the selected color, the seller, and the return window. |
| Walmart | Item 10741057, white 36-inch Carlson gate | Enter your ZIP code to confirm shipping or pickup, and check who sells and ships it. |
Compare the delivered total for the same model and bundle. If prices are close, choose the seller with the return option that works best for you. The included extension and mounting parts matter more than a small price difference if your doorway needs the wider configuration.
What you’ll notice in daily use
The large swing door saves you from stepping over a 36-inch barrier, but its clear opening is only 16.5 inches according to Carlson. Measure the width of anything you carry through that doorway regularly, such as a laundry basket or pet carrier. Also check the door’s swing against nearby furniture and the room door.
The small flap measures 7.5 inches wide by 7.75 inches high on Carlson’s spec sheet. Measure the smaller pet and think about the dog you want to keep out. If the dog can use that flap too, keep it latched. If the flap is central to your setup, our walk-through gates with cat doors guide covers other layouts.
What to check before installing
- Match the model number on the box to the manufacturer’s specifications and follow the manual supplied with the gate.
- Inventory the frame, extension, and mounting hardware before installation. Use the wall cups and fasteners as directed by Carlson.
- Test the walk-through latch and small flap before relying on either. Check that the gate closes correctly after adjusting the mounting points.
- Choose a gate explicitly rated for top-of-stair installation if that is where you need a barrier. Follow the manufacturer’s instructions for that location.

Common questions
Will this model fit a 33-inch doorway? No. The 33-inch measurement is between the standard and extended fit ranges for this white 0941 model.
Does the 4-inch extension come in the box? Carlson lists it in the standard package. Check that the selected retailer offer includes it, particularly on open-box or marketplace listings.
Is 36 inches enough for a dog that jumps gates? It depends on the dog’s reach, climbing behavior and motivation. If your dog already clears barriers this high or pushes them out of place, choose a more suitable setup.
What if I need a wider or taller opening? Start with the actual width and height your space needs, then compare the options in our extra-tall and wide pet gate guide.
