## Summary description

3M Dual Lock Fastener SJ354B is a flexible, reclosable fastening strip 25 mm wide and 2.5 m long in black. The product provides a strong interlocking mushroom-head closure for removable mounting, cable management, panels and light fixtures. It suits repeated opening/closing, offers vibration resistance and simple peel-and-stick installation on compatible surfaces.

## Long description

3M Dual Lock Fastener SJ354B 25mm x 2.5m in black is a flexible reclosable fastening tape designed to provide a secure, low-profile connection between two surfaces. The product consists of interlocking mushroom-shaped stems that snap together to form a strong, removable bond. Supplied as a 25 mm wide roll with a 2.5 m length, this Dual Lock solution is intended for applications where repeated opening and closing is required without the need for mechanical fasteners.
Advantages
The flexible construction allows the fastener to conform to curved or irregular surfaces while maintaining reliable engagement. The interlocking mushroom heads deliver consistent retention and can be separated and rejoined many times without significant loss of performance. Its low-profile design minimizes visual impact and bulk when installed. The black color provides discreet appearance on dark surfaces and helps hide wear over repeated use.
Suitable for
Reclosable panel and access door attachments
Mounting electronic modules and small devices that require periodic removal
Securing trim, cable management elements, or lightweight housings
Temporary fixtures, displays, and signage that need repeated service
Key specifications
Width: 25 mm
Length: 2.5 m roll
Color: Black
Flexible fastener with interlocking mushroom-shaped stems
Reclosable/reusable fastening mechanism
How to use
Clean and dry both surfaces before application to ensure optimal adhesion and engagement of the interlocking stems. Measure and cut the required length from the roll, then align and press the two mating strips together so the mushroom-shaped stems engage. For best results on curved surfaces, apply pressure along the strip to conform it to the substrate. To separate, peel the strips apart with a controlled pulling motion; avoid sharp lateral twisting that could damage the stems.
Usage recommendations
Use on clean, smooth substrates for the most consistent performance. Avoid prolonged exposure to solvents or sharp mechanical abrasion. For heavy loads or critical safety applications, evaluate load capacity in actual use conditions and consider mechanical fasteners or additional attachment methods if required.
