Review on 👷 Enhancing Workplace Safety with Mr Occupational Health & Safety Facility Products by Logan Tripp

This is a great alternative to the MUCH more expensive metal models you usually see. Don't think that you fill them with water instead of sand to make them stronger. The base is not closed, so they are not very stationary. A little push and some of them will fall. However, they are cheap and come with a ton of plastic chain.
