• Dual Lock 400 - has a dense stem pattern of approximately 62 stems/cm². It locks together in any position and is generally the best choice for joining two surfaces when using the Pressure-Sensitive Dual Lock products.
• Dual Lock 250 - has approximately 38 stems/cm². It is a self-engaging fastener providing similar strength to Type 400 to Type 170 combination. It also reduces inventory as only one roll is required.
• Dual Lock 170 - has approximately 26 stems/cm². Besides general use with Dual Lock Type 400, it can also be mated to Scotchmate Loop products to provide an excellent high strength fastener with a limited re-closure life.
