Dual-Lock velcro
Dual Lock hook-and-loop fastener (mushroom heads) – extremely strong and repeatedly reusable next-generation fastening
Dual Lock hook-and-loop fastener, often also referred to as a “mushroom-head” fastener, represents an advanced alternative to classic hook-and-loop fasteners. This system uses special plastic mushroom-shaped heads that, when pressed together, interlock and create an exceptionally strong and stable bond. Unlike the traditional hook system, it guarantees even force distribution, high tensile and shear strength, and a long service life.
Professional quality and structural strength
3M Dual Lock is made of durable polyolefin, which resists UV radiation, heat, moisture, and chemicals, making it ideal for indoor and outdoor use.
Once the mushroom heads snap together, a strong mechanical connection is created that can withstand high loads, while still being releasable at any time without damaging the material. The joint remains discreet, clean, and requires no tools.Universal use in industry, transport, and interior design
Dual Lock reclosable fasteners are used for mounting panels, covers, illuminated signs, vehicle interior components, electronic devices, exhibition structures, or structural parts.
They are especially popular wherever high joint strength is required, along with the possibility of easy disconnection. They can also be combined with a 3M VHB™ adhesive layer, which ensures immediate adhesion without the need for drilling or screwing.Main advantages of the 3M Dual Lock system (mushroom heads)
-
Extreme bond strength – up to 5× stronger than classic hook-and-loop fastener
-
Reusable usability – the possibility of more than 1000 connection and disconnection cycles
-
Resistance to UV radiation, temperature, and humidity
-
Clean and quiet connection without dust and fibers
-
Easy application – also available in a self-adhesive version
-
Compatibility between different types (e.g. 3M SJ3550, SJ3560, SJ3870)
A practical and elegant connection without drilling or screws
Applying Dual Lock is simple – the strips are adhered to both surfaces, pressed together, and the bond is immediately functional. Disconnection is possible simply by separating the two parts, while there is no damage to the substrate or loss of adhesion. The joint is sufficiently strong for structural as well as aesthetic applications, where a professional appearance without visible fasteners is required.
The Dual Lock hook-and-loop category (mushroom heads) represents the most advanced technology for reusable fastening. It combines high mechanical strength, easy handling, and long service life, making it an ideal choice for professional installations, designer applications, and technical uses, where it is important to combine strength with elegance and practicality.
