Retention pans Retention pans are designed to safely collect accidental or regular spills, including meat and fish exudates, fresh produce residues, detergents, disinfectants, oils, solvents, and water from defrosting, washing or condensation. The retention pans combine strength and lightweight construction thanks to their stainless steel and aluminium design. Each system includes two stainless steel hooks fixed to the rack side rails and a flat-bottom aluminium sliding collection tray. For useful lengths of 1010 mm or more, the system is supplied with four hooks and two trays. PDF leaflet
