Permanent splices for heavy duty belts

The only flexible screw splice in polyurethane

To meet the most extreme environments and the most demanding requirements, MLT created the SUPER-SCREW®* PREMIUM: the first flexible splice to screw in polyurethane, designed for extremely abrasive applications*.

The polyurethane that composes the upper part of this new SUPERSCREW®* splice provides a considerable gain in abrasion resistance (15 mm3) while maintaining the flexibility, perfect integration, and strength of SUPER-SCREW®*.
