Rejuvenator flooring features large 3'x3' modules--and now new 1'x3' modules as well-- that interlock on all 4 sides to customize on-site virtually any flooring configuration. The interlock is incredibly effective--and also hidden--so the ergonomic floor you've created is seamless and stable underfoot. Having the ability to customize in 1 foot increments and finish off with beveled ramps [yellow or black] sets Rejuvenator Flooring apart from all other urethane wannabees.
