Mastiff Dog Ute Cage

The Mastiff model dog cage has been designed to suit most steel and alloy ute trays. In the standard orientation the dog cage spans the width of a standard dropdown tray. Because of their size these cages are fabricated using heavier duty materials. It’s design allows the cage to be installed anywhere along the length of the ute tray, whether it be the front, rear or middle of the tray.

Mastiff model dog boxes can easily accomodate multiple small, mediam and large breed dogs.

Add-on Features

Our Mastiff dog boxes can be heavily customised. Swing away partitions are a great way to divide dogs that don’t like travelling together. Roperails add additional storage to the vehicle while rear facing doors are easier for loading some dogs.

As the Mastiff dog box is our “budget friendly” model to suit these tray types it comes standard with overcentre latches that can be padlocked. The doors can be upgraded to a more secure key lockable door for a small cost.

Of course, as with all our dog boxes powder coating can be arranged in almost any colour.


The default dimensions for these dog boxes are 1700x600x838H.

We can also fabricate this dog cage to be the “full width” of the tray to allow for the tray sides to be cut down. Cutting down the sides of the tray does involve some work, but adds the convience of not having to drop the sides to open the dog box doors.

Two 50mm angles run the length of the dog cage allowing it to be easily bolted into the tub.


Our Mastiff dog boxes start from $1150.00+gst for mill finish. Additional extras include powder coating (plus $250.00), roperail, and internal dividers.

Freight varies anywhere from $140.00 – $400.00. The cheapest option is to arrange delivery to another business address or collect it from a depot. Due to the size of this model residential delivery can be very expensive. For a freight quote be sure to include your postcode in your enquiry
