National Safety Apparel M60GNRH1420 Aluminized Fiberglass Reversible Heat Mitten

The National Safety Apparel (NSA) M60GNRH1420 is a new, reversible aluminized fiberglass mitten engineered for extreme radiant heat and molten metal splash protection in heavy industrial environments such as foundries, steel mills, smelting operations, and glass manufacturing. Decoding the model number: "M60G" designates the aluminized fiberglass shell material (60-weight aluminized fiberglass fabric), "NR" indicates a no-lining reversible construction (both the palm and back are identical aluminized fiberglass, allowing either side to face the heat source), "H" denotes the mitten/hand configuration, "14" encodes the 14-inch length measured from fingertip to cuff, and "20" specifies a size 20 (one-size, XL/universal fit). The aluminized outer shell reflects radiant heat while the mitten silhouette — featuring a sewn thumb stall and snap closure at the gauntlet cuff — maximizes hand protection and prevents the mitten from being pulled off during handling. NSA's aluminized fiberglass fabric is rated for sustained contact temperatures and radiant heat exposure consistent with ASTM F2412/F2413-referenced thermal hazard environments; the reversible design doubles service life by allowing the operator to flip the mitten when one side is soiled or worn. Snap fasteners at the wrist allow the pair to be stored together and facilitate quick donning in high-production settings.
