About this item
SKU DK3M111 — 150' × 1", Polyolefin, Black. Sold as a case of 2, shipped from US warehouses.
Industrial-strength 3M Dual Lock reclosable fasteners deliver hundreds of secure closures without compromising durability. Each case includes 2 rolls of 150-foot black polyolefin tape with Type 170 stem density, engineered for heavy items and low-surface-energy materials. Works up to 120°F for indoor packaging applications.
Common questions
Can this fastener be used on flexible or low-surface-energy plastics?
Yes. The rubber-based adhesive is specifically engineered to bond reliably to polyethylene, polypropylene, powder-coated paints, and other low-surface-energy materials that standard adhesives struggle with. This makes it ideal for modern plastic equipment housings and composite surfaces.
How many times can this fastener be opened and closed?
Type 170 Dual Lock fasteners support hundreds of reclosure cycles without losing grip strength. The rigid plastic stems interlock mechanically rather than relying on adhesive bonding alone, ensuring consistent performance across extended product lifecycles.
Which 3M Dual Lock products are compatible with this Type 170 fastener?
Type 170 fasteners interlock exclusively with Type 250 and Type 400 Dual Lock products. It does NOT interlock with itself, so you must use a compatible mate strip. DK3M115 and DK3M128 are compatible hook-and-loop partners.
What is the practical coverage area per case?
Each case contains 300 linear feet (2 rolls x 150 feet) of 1"-wide fastener. For typical 1" x 1" fastening points, you get approximately 300 separate attachment locations, making this ideal for high-volume manufacturing runs and assembly operations.
