Four wheel dollies were pretty easy to assemble. Four pieces of wood, four casters (hopefully the same size) and maybe a couple strips of carpet to staple, tack, or glue on the rests. That was it. Now they’re stronger. Built with different material other than wood, that won’t crack or splinter and can hold much more weight than the dollies of old.
Polyethylene dollies are made of high impact and durable polyethylene construction. Unlike it’s wooden counterparts, these dollies are easy to clean with a non porous platform that will not splinter, mildew or rot. Polyethylene dollies can withstand the weather and will continue to perform without worries of warping from moisture. They are available with different casters for different applications and can be interchanged easily.
