3-4 WEEKS LEAD TIME80mm AISI 316 grade stainless steel castor complete with full swivel wheel brake and M12 bolt hole fitting. These 316 stainless steel swivel casters are resistant to corrosion and can handle the harshest environments even when salts or aggressive chemicals are present. Due to the high salt spray content within the offshore and marine industry, we would recommend using these castors. As well as being marine grade castors other applications include the food, hospital and medical industry.
