The FarmIT weighing crates all use a standard aluminium lug. This is very similar to those used on a number of sheep handling systems and are designed to allow a certain amount of flexibility when connecting hurdles. The oval hole design allowing more give when laying out the equipment on uneven ground.
Given the rather ruff handling that hurdles and weigh crates get during daily usage, lug tend to take the strange and often get broken or over time simply wear. We therefore decided to make lugs available as a spare part for you to carry out your own repairs.
