Usage

Designed for versatility, the Dual Lock SJ3560 Clear strip excels in both indoor and outdoor environments. It is ideal for mounting removable components such as panels, signage, lighting fixtures, and equipment housings where quick access and secure attachment are required. The clear material makes it especially suitable for applications where visual aesthetics matter, such as display cases, retail fixtures, and transparent enclosures. Its high‑temperature resistance allows it to be used in automotive interiors, aerospace panels, and industrial equipment that may experience heat exposure during operation or cleaning processes.

Installation is straightforward: simply peel away the protective liner and press the adhesive side onto a clean, dry surface. The strip can be cut to any length with scissors or a utility knife, eliminating waste and enabling custom sizing for irregular shapes. Because the fastener is reclosable, maintenance crews can easily replace or reposition components without damaging the underlying substrate, reducing downtime and labor costs.

Installation Guide

Begin by cleaning the target surface with a mild detergent and allowing it to dry completely. Remove the protective liner from the adhesive side of the Dual Lock strip, taking care not to touch the adhesive surface. Align the strip with the desired placement and press firmly for at least 30 seconds to achieve a secure bond. For larger areas, use a roller to ensure even contact across the entire length. If the strip needs to be shortened, cut it with a sharp pair of scissors or a utility knife, then reapply the adhesive backing to the newly cut edge.

After installation, test the connection by pressing the two sides together and pulling them apart. The fastener should snap securely and release with a gentle pull, confirming proper engagement. For optimal performance, avoid exposing the adhesive to extreme moisture or solvents during the first 24 hours after installation.

Performance Benefits

The Dual Lock system delivers superior shear and peel strength compared to conventional hook‑and‑loop products, thanks to its engineered interlocking heads. This translates to higher load‑bearing capacity and reduced risk of accidental disengagement. The clear material also offers UV stability, preventing yellowing or brittleness when exposed to sunlight for extended periods. In addition, the fastener’s ability to be reused thousands of times reduces material waste and aligns with sustainability initiatives.

Customers report faster assembly times, lower inventory costs, and improved product aesthetics when switching to Dual Lock. The fastener’s versatility enables it to replace a wide range of hardware, from screws and bolts to traditional Velcro, simplifying supply chains and streamlining design processes.

FAQ

Can the Dual Lock strip be used on painted surfaces?

Yes, the adhesive backing adheres well to clean, dry painted surfaces. For best results, ensure the paint is fully cured and free of dust or oil before application.

How many times can the fastener be opened and closed?

The mushroom‑head design is engineered for thousands of re‑engagement cycles without loss of holding power, making it ideal for applications that require frequent access.

Is the clear material UV resistant?

Absolutely. The clear plastic formulation includes UV stabilizers that prevent yellowing and maintain structural integrity even after prolonged exposure to sunlight.

What is the recommended temperature range for installation?

Installation should be performed at temperatures between 50 °F and 86 °F (10 °C to 30 °C) for optimal adhesive performance. The fastener will continue to function effectively within the broader operating range of -40 °F to 200 °F.

Can the fastener be removed without damaging the surface?

When removed carefully, the adhesive may leave a minimal residue that can be cleaned with a mild solvent. The underlying surface is generally not damaged, especially on smooth, non‑porous materials.
