Magna-Tronce is a flexible sheet of silicone with permanent magnets embedded in the sheet. The Magna-Tronce Mat is designed to keep delicate surgical instruments firmly and safely in place, even during the most critical operations. Embedded magnets hold surgical instruments in convenient positions, and eliminate most of the dropped instrument problems. The flexible Magna-Tronce Mat may be clamped to drapes on any slanted or uneven surface. Grommets are provided at the corners so that the magnetic sheet may be tied or clamped in any position. Magna-Tronce Mat is capable of being autoclaved. A film of silicone protects embedded magnets. 11-7/8" x 11-7/8" (30 cm x 30 cm)
