Dual Lock SJ3560 Reclosable Fastener 2in x 7.5ft - Heavy Duty Mounting

In this review the Dual Lock SJ3560 Reclosable Fastener earns its place as a utility item for DIYers, installers and light industrial users who need a clean, reliable removable bond. The single biggest reason to buy is its combination of high tensile strength and a pressure-sensitive acrylic foam tape that sticks to many surfaces without drilling. For those who need a hidden, repeatable fastening solution that holds panels, graphics or small components, this product delivers a durable, low-profile alternative to screws or mechanical fasteners.

Key Features

• High stem density: The 250 stems per square inch design provides up to five times the tensile strength of typical hook and loop, making it suitable for demanding attachment tasks.
• Interlocking mushroom heads: The self-mating interlocking profile gives a positive audible snap that confirms secure fastening and keeps joined parts aligned.
• Conformable acrylic foam tape: The pressure-sensitive adhesive bonds well to metals, glass, hard wood and many plastics for a stable long-term connection.
• Reusable performance: Rated for up to 1,000 open/close cycles while retaining roughly half its original strength, so it works for removable panels and service access.
• Weather and chemical resistance: The foam tape resists heat, UV and many chemicals, which helps maintain adhesion in indoor and outdoor settings.
• No tools required: Installation needs only pressure to adhere, avoiding drilling, screws or sewing and saving time on simple mounting jobs.

Who It's For

This Dual Lock is best for hobbyists, sign and graphic installers, vehicle interior fitters and light manufacturing where parts need a strong but removable bond. It is particularly useful for securing access panels, attaching graphics, and mounting small components without visible fasteners.

Those who should look elsewhere include users who need an adhesive that will never lose more than a small amount of strength after repeated cycles or anyone working exclusively on delicate painted surfaces where testing is required, since there are mixed reports about paint resistance on some finishes.

Pros & Cons

Pros

• Exceptional holding power compared with standard hook and loop, thanks to 250 stems per square inch.
• Strong initial adhesion to a wide range of substrates from metal to acrylic because of the conformable acrylic foam tape.
• Clean, hidden fastening that snaps audibly and supports repeated opening and closing for service panels.
• Easy, drill-free installation that resists heat, UV and many chemicals for outdoor use.

Cons

• May pull paint from some painted surfaces, so test on a small area before full application.
• Retains about 50% strength after extended cycles, so not ideal where original bond strength must be preserved entirely.

Our Verdict

The Dual Lock SJ3560 is a practical, value-oriented choice for anyone needing a high-strength, low-profile removable attachment. It replaces visible mechanical fasteners in many light industrial and DIY applications and performs reliably on metals, plastics and glass. Purchase it when you want strong reusable fastening without tools, but pretest painted surfaces and avoid use where full original strength must remain after extensive cycles.

Frequently Asked Questions

Will this stick to painted surfaces?
It bonds to many painted surfaces but there are mixed reports; test on a small area first to check for paint removal.

How many times can it be opened and closed?
The product is rated for up to 1,000 open/close cycles and will retain about 50% of its initial strength after extensive cycling.

Does it require tools to install?
No, the pressure-sensitive acrylic foam tape adheres on contact and needs only firm pressure to install, no drilling or screws required.
