3M Dual Lock^TM Plain Backed Reinforced Reclosable Fasteners (Types 400 and 170)
SJ-3443  SJ-3444

• The Fasteners can be sewn-on, stapled, washed or dry cleaned.

• They have passed F.A.R. 25.853 (b-2),(b-3), and FMVSS302 when attached to flame resistant fabric .

• The operating temperature range is -29C/-20F to 93C/200F continuous. 

• Hundreds of mushroom-shaped stems interlock with one another when these fasteners are pressed together. An audible snap indicates the fastener is locked. This fastener has a tensile holding strength more than 5 times greater than the 3M^TM Scotchmate^TM Hook and Loop Reclosable Fasteners. 

• Also, it is stronger than the standard products (SJ-3444, 41 and 42 Series).

• Mating Type 400 and Type 170 stems provides the most universal Dual Lock Fastener combination. When closure involves two flexible surfaces,

• Type 400 can mate with itself.

• Type 170 can mate with Scotchmate loop products.

• Type 250 provides a more dense product for rigid surfaces if you need a  stronger bond than that of Type 170.
