3M Dual Lock Type 250 Reclosable Fastener Features
-
3M SJ3540 Dual Lock 250 Reclosable Fastener (Rubber Adhesive) is a general-purpose black reclosable fastener with 250 stems per square inch, an engaged thickness of 0.23 inches and a closure life of 1,000. This black fastener has mushroom-shaped stems on a polypropylene carrier which is coated with a rubber adhesive.
-
Type 250 stem density fasteners can mate to type 170, 250 or 400 fasteners (the higher the combined number the greater the closure strength). Mushroom-shaped stems on one side of the fastener interlock with identically shaped stems on the other side for 5X greater closure strength than hook and loop.
-
Dual lock type 250 fasteners with rubber adhesive are designed to bond to plastics, powder-coated metal and other low surface energy (LSE) substrates. They can replace conventional fasteners such as screws, clips, rivets, snaps, hook and loop and bolts in many applications where access or repositioning is needed.
-
Used to hang indoor signs or art, cushions, wall headliners, indoor display components, ceiling attachment, privacy curtain rails, and wall panels. Also for POP (point of purchase), trade show exhibition and electronics, and for attaching E-ZPass tags to car windshields.

Dual lock only has one type of side; unlike velcro where there are a separate hook and a loop side; so rolls are typically cut in half and then mated or connected so a 10-foot roll would be used as two 5-foot strips.
