Dual Lock
Tough Alternative To Mechanical Fasteners

Dual Lock 400/170
Dual Lock fasteners are intended to replace mechanical-type fasteners while retaining the blind fastening, adjustability and ease of use hook & loop fasteners offer. The types refer to the number of stems or mushrooms per square inch. Type 400 mates to itself, providing maximum strength. Often this is too much holding power. So we also offer Types 170 and 250.

Type 170 mates to Type 400 for less strength, or to loop for a semipermanent closure. Six different combinations are possible in the Dual Lock family to achieve the ease of release youíre looking for. Dual Lock products are typically available in 1/2" - 4" widths.


Dual Lock 250
Type 250 mates with itself or with Type 400 to achieve just the right amount of holding power. Type 250 is also available clear to better blend with your product.
