The NEW Ultra Flex-Pen™ - The Ultimate Indoor Pen Solution - Calf Hutch

The NEW Ultra Flex-Pen™ – The Ultimate Indoor Pen Solution

June 1, 2020, Sidney, NE – Agri-Plastics, the Calf Housing Specialists, have been making calf hutches since 1995. The first product the VanBuuren family developed was an outdoor hutch made for one calf. Over the years, Agri-Plastics created a variety of outdoor hutches and expanded its product offering to include a variation that works for indoor barn operations. Introducing the Ultra Flex-Pen: a versatile indoor pen system for individual or grouped calves.

The Importance of Stressless Transitions

blankThis versatile housing system was developed so that single pens could convert to a group pen simply by detaching a side panel. This innovative, stand-alone solution allowed calves to be housed individually, then grouped when health permits. By keeping stress levels down, calves have a better chance to grow strong and healthy. They also learn how to socialize within smaller groups. Therefore, it helps ease the transition into a larger herd.


Evolving the Flex-Pen to the next level

Pens need to be durable and strong, but also lightweight so they are easy to move. So Agri-Plastics developed the next generation of indoor transition pens – The Ultra FlexPen. A new compression molding process keeps the panels lightweight. Smooth surfaces and curved edges make it easy to clean. Ventilation is also very important, so a large rear rotary vent helps control airflow.


The new Ultra Flex-Pen features include:

  • Ultra lightweight for easy setup and cleaning without jeopardizing durability
  • Self-aligning panels use EZ-Glide Connection Tabs and Hinges for easy and quick setup
  • Ultra bio-secure
  • Ultra rear rotary venting has no steel wire to rust, fully adjustable air flow control, and no separate parts to lose or store
  • Optional Integrated sliding side panel vents for additional air control from side to side
  • Individual penning used to maximize pens per room size
  • Individual pens interlock together for a clean line of calf spaces
  • Center panels can be removed to create a group penning option
  • Ultra pen access with a bi-swing front door for maximum flexibility
  • Large egronomically-designed door handle
  • Ultra tough, non-metal door frame made with a structural compression molding process
  • Ultra Flex-Pen panels available in a 5’, 6’, and 7’ lengths to fit any size barn operation and allows for optimum calf space
