3M 7100112902 Dual Lock Reclosable Fastener 5/8in X 50yd

Product Description

The 3M 7100112902 is a low-profile Dual Lock reclosable fastener supplied on a 50-yard roll, 5/8 inches wide, in black polypropylene. It uses a low surface energy (LSE) adhesive backing that bonds to metals, glass, and a wide range of plastics without requiring primers on most surfaces. The engaged thickness measures 0.105 inches, keeping the fastener nearly flush when closed. Rated for 100 closure cycles, it is suited for repeated-access panel attachments, cable management, and component mounting in interior applications. HVAC techs, electricians, and assembly professionals use this fastener where screws or rivets are impractical.

This fastener is designed for indoor use across light commercial and residential applications. It performs in low to medium temperature environments, with a rated temperature resistance of 158 degrees F. Compatible substrate list includes aluminum, stainless steel, glass, polypropylene, polyethylene, polycarbonate, ABS, and powder-coated paint surfaces. It is appropriate for securing access panels, wire looms, lightweight covers, and interior trim components where a clean, tool-free reclosable connection is required.

Key Features

• Low surface energy adhesive backing bonds to plastics, metals, glass, and powder-coated surfaces
• 0.105-inch engaged thickness for a near-flush, low-profile closure
• 100-cycle closure life supports repeated open-and-close service access
• Black polypropylene construction resists moisture and minor chemical exposure indoors
• Temperature resistance to 158 degrees F for low to medium heat environments
• 5/8-inch width by 50-yard roll allows field cutting to required lengths

Compatibility

Designed for use on metals (aluminum, stainless steel), glass, polypropylene, polyethylene, polycarbonate, ABS, powder-coated paints, and other medium to low surface energy materials in indoor environments.

Installation Notes

Surface must be clean, dry, and free of dust, oil, and loose particles before applying the adhesive backing. Apply firm pressure across the full length of the fastener strip to ensure full adhesive contact. This product is intended for indoor use only — do not install in outdoor, high-humidity, or high-temperature environments exceeding the rated limit. No tools are required for closure, but proper surface prep is critical for rated adhesion performance.
