Key Features of the Open Air Flex-Pen System:

Front and Rear Metal Panels: The inclusion of galvanized steel front and rear panels facilitates exceptional air circulation while allowing easy visual access to monitor calf health and behavior.

Effortless Transition: Like its Ultra Flex-Pen counterpart, this system effortlessly transitions from single to group housing simply by detaching the side panels, providing flexibility in calf management.

Integrated Sliding Side Vents: Complying with specific regional regulations, the Open Air Flex-Pen System incorporates integrated sliding side vents, ensuring optimal ventilation for calf comfort.

Versatile Configuration: The system allows for versatile configurations, including single, paired, or group housing. It also features the Ultra Flex-Pen Group Housing bar for connecting multiple pens.

Detachable Center Panel: The lightweight indoor pen includes a detachable center panel, enabling grouping or individual housing for calves based on health or welfare needs. Pens can be extended to any desired length.

Ease of Setup and Cleaning: With self-aligning panels that use EZ-Glide Connection Tabs and Rods, the system is easy to set up and clean without compromising durability.

Bio-Security: The Open Air Flex-Pen System is designed with bio-security in mind to ensure the health and safety of your calves.

Modular Free-standing Design: No need for posts or floor installations; the units are modular and can be expanded effortlessly. They can also be wall-mounted using an optional wall mounting bracket.

Bi-Swing Front Door: The system includes a bi-swing front door for easy access, and a slam latch keeps the front gate secure.

About Agri-Plastics: The VanBuuren family founded Agri-Plastics in 1995. These third-generation dairymen know first-hand the difficulties experienced on a dairy farm. They began experimenting with hutch designs to provide healthier, more comfortable environments for calves. Over the years, Agri-Plastics has listened and learned from many other producers, and they have used that knowledge to create game-changing innovations that have since become industry standards.
