If you order our Fab System rail assembly, you do NOT need these corner pieces. The rail assembly comes complete with everything you need to insert rails into your whelping box.
However, for those that prefer do-it-yourself rails or those looking to save shipping money on rails, these 4 corners allow you to easily make your own rails from standard wooden 2x4 studs. Studs fit nicely into these corner moldings. Four ABS plastic corners are included. Screws and nuts are not included.
These moldings are specially designed to keep puppies from getting stuck in whelping box corners. Angled legs steer puppies away.
Use with the Fab Box, the Classic Value Box, or any whelping box!
