This mat trolley is made with a robust tubular steel frame, 1.92m long x 1.35m high x 0.62m wide to hold up to 14, 1829 x 1219 x 25mm (6' x 4' x 1'') mats or 28, 1291 x 914 x 25mm (4' x 3' x 1'') mats. Non-marking rubber wheels. Sold individually. It is best to move the mats around by trolley. Avoid bending and pulling mats around by their corners. Most damage occurs during handling and transportation so care here will prolong the life of the mats.
