A 4 Pet 40-Inch Collapsible Soft Dog Crate for Travel with a Steel Frame

A 4 Pet’s 40-in (101.6 cm) collapsible soft dog crate gives medium to large, well-trained dogs a travel-ready enclosure with a reinforced steel tube frame and two folding options.

• Full-length steel tube frame without middle folding joints — helps the crate hold its shape without wobbling.
• Patented screw-tightening twist-lock design — tightens the fabric, with tool-free, one-handed setup in under 30 seconds.
• Two ways to fold — flatten the crate or collapse it into a compact bundle without disconnecting parts.
• Waterproof-lined floor and removable, washable cover — make cleanup and surface protection easier.
• Three mesh windows and roll-up side entrances — provide airflow, visibility and access from the sides.

A soft crate can be useful when a dog needs a familiar indoor enclosure, a place to rest on the road, or a setup that can move between rooms. A 4 Pet combines a framed structure with a fabric cover, then folds away for storage or travel. Its intended users are medium to large, well-trained dogs; the 40-inch length is the key size to compare with your dog’s resting space.

What dogs is this 40-inch crate designed for?

This crate is intended for medium to large, well-trained dogs. Its full-length steel tube frame keeps the fabric enclosure taut, and the frame design avoids middle folding joints. That construction is intended to hold the crate’s shape and reduce wobbling during everyday use. The 40-inch length gives you a concrete starting point when judging whether the enclosure suits your dog and the space where you plan to use it.

• Designed for indoor use as well as travel and transitions between rooms.
• Roll-up side entrances let dogs enter and exit without a door swinging into the space.

How does the crate fold and set up?

You can fold the entire crate flat or collapse it into a compact bundle, with no parts to disconnect. The patented twist-lock uses a screw-based frame to tighten the fabric, helping it stay taut and reducing sagging. Setup is tool-free, takes under 30 seconds and can be done with one hand.

• The flat-fold option suits storing the crate under a bed, in a closet or in an SUV trunk, where space allows.
• The compact-bundle option supports packing it away between uses or moving it between locations.

How do the cover and base handle everyday mess?

The removable fabric cover fastens with a zipper and is washable, while the crate floor has a waterproof lining. Remove the cover for cleaning, and wipe the lined base when dirt or a small spill needs attention. The floor design does not rely on a loose crate pan or a plastic tray replacement.

• The waterproof lining helps protect the surface beneath the crate from dirt and small spills.
• The cover comes off by zipper for cleaning and can be put back on after washing.

How do the windows and entrances support use at home or on the road?

Three mesh windows provide airflow and visibility from multiple sides. The breathable, visible design is intended to help dogs feel calmer indoors or during road travel. Roll-up side entrances give access without sharp parts or stressful noise, keeping entry and exit simple.

• Mesh panels allow a dog to see out while providing ventilation.
• Side entrances roll up when access is needed.

A 4 Pet is suited to people looking for a soft crate for a medium to large, well-trained dog that can serve at home and travel, then fold away when it is not in use. Its steel tube frame, two folding options, washable cover and waterproof-lined floor bring structure, storage flexibility and practical cleanup together in one 40-inch enclosure.
