PRODUCT DETAILS

4th Gen Adjustable Crash-Tested Dog Car Crate
Product overview
The MIMSafe VarioCage Single Large is an adjustable dog car crate designed to provide a secure, protective space for one dog during vehicle travel while leaving room in the boot for luggage. Its telescopic construction allows the depth to be adjusted to suit the available boot space, helping you make better use of your vehicle without compromising the protected space around your dog.
Part of the 4th generation VarioCage range, this single dog crate combines a controlled deformation zone with a strong, energy-absorbing structure designed for vehicle transport. It is suitable for SUVs, estate cars and hatchbacks when correctly installed behind the rear seat.

Key features
- Crash tested: Tested using the SPCT (Safe Pet Crate Test) method, covering frontal impact, rear impact and rollover-related loading.
- Adjustable depth: Telescopic construction allows the crate depth to be adjusted for a better fit in your car boot.
- Built-in crumple zone: The telescopic structure is designed to compress in a controlled way during a collision.
- Emergency exit: A dedicated escape hatch provides an alternative extraction point if the main door becomes blocked.
- Gas-assisted door: Gas springs help hold the door open when needed.
- One-hand quick release: Makes opening and closing the door straightforward.
- Built-in lock: The door has an integrated lock system with key included.
- Additional locking: Provision is included for an additional lock if required.
- Single-dog design: Provides one protected compartment while retaining useful luggage space alongside the crate.
Safety
The VarioCage Single has undergone rigorous crash testing at RISE Research Institutes of Sweden using the SPCT (Safe Pet Crate Test) method. The test protocol covers three relevant crash scenarios for a dog crate: frontal impact, rear impact and a corner-drop test designed to replicate the effects of a vehicle rollover. The crash pulse used is based on ECE Regulation No. 17.
The built-in deformation zone is designed to allow controlled compression along the vehicle's crumple zone during a collision, helping reduce the risk of direct impact being transferred towards rear-seat passengers. The crate is designed to be shockproof in all directions.
The VarioCage should be installed behind the vehicle's rear seat and secured to the vehicle's cargo loops. When installing the crate, use at least two straps to secure it in the boot and prevent movement during transport.
After a collision, the VarioCage should be taken out of use. Its energy-absorbing deformation zones are intended to work as part of the crash protection system and may be compromised after an impact.

Materials & construction
The VarioCage is constructed from galvanised steel with a weather-resistant powder-coated finish. The structure uses splinter-proof and energy-absorbing materials and is designed to provide protection from impacts in multiple directions.
The door incorporates reinforced construction, a built-in lock and gas-assisted opening. Door handles can also be used as convenient storage pockets.
Size & dimensions
The correct VarioCage size should be chosen according to both your vehicle's available boot space and your dog's size. As a guide, the dog's height at the withers plus 5 cm should fit within the cage's internal height (H2). For this Large model, that gives a recommended maximum withers height of approximately 58 cm.
- Adjustable exterior length: 70–91 L cm
- Exterior width: 55.5 W cm
- Exterior height (H1): 65 H cm
- Door threshold height (H3): 63 H cm
- Internal height (H2): 63 H cm
- Internal length: 64–85 L cm
- Internal width: 50.5 W cm
- Weight: 17.5 kg
- Recommended maximum dog height: approximately 58 cm at the withers

Always check the available width, height and boot-floor length of your vehicle before ordering. The tailgate opening and wheel arches can affect the usable space, so measuring the narrowest and lowest points is important.
