The Northwest Territory 14x12 Screen House tent is a large, screened-in canopy designed to provide a sheltered, bug-free outdoor living space. The "Opened/ No Cardboard Box in Bag" description indicates that it is a used or open-box item that is missing its original packaging. 

Features and uses

• Protection: The screen house protects against insects, rain, and UV rays, making it ideal for camping, picnics, or backyard gatherings.
• Dimensions and size: It measures 14 feet by 12 feet, providing up to 132 square feet of interior space. This is generally enough room to fit over a standard picnic table.
• Construction: It features a durable frame, typically consisting of a combination of steel and fiberglass poles.
• Vented roof: The roof is vented to allow for air circulation, which helps keep the interior cool on warm days.
• Zippered doors: The screen house has two zippered doors for convenient entry and exit.
• Mesh walls: Its mesh walls provide excellent ventilation while keeping out flies, mosquitoes, and other pests.
• Portability: It comes with a polyester carry bag for transport and storage. 

How to use

1. Lay out the tent: On a level patch of ground, take the frame out of the bag and spread it out. You will likely need another person for this step.
2. Drape the fabric: Lay the tent fabric over the partially opened frame.
3. Assemble the poles: Insert the poles into their designated sleeves to build the roof and expand the structure.
4. Extend and secure the frame: Fully extend the frame until it clicks into place. Depending on the exact model, this can be done by pulling the legs outward or pushing up a central hub.
5. Stake it down: Anchor the screen house to the ground using the included stakes and guy lines for stability, especially if it is windy. 

Important considerations

• Opened box: Be aware that "Opened/No Cardboard Box" means it is a used product, so check for any missing parts or signs of wear upon receipt.
• Manufacturer: The Northwest Territory brand was historically associated with Kmart and Sears, and their products are now commonly sold on marketplace sites like eBay.
• Wind resistance: Screen houses are not as sturdy as dedicated tents in strong winds. If high winds are expected, make sure it is properly staked and secured, and consider a more robust shelter.
