Dual Lock^™ 400/250/170

Dual Lock^™ fasteners are intended to replace mechanical-type fasteners while retaining the secure fastening, adjustability and ease of use that Dual Lock fasteners offer. 400/250/170 refer to the number of stems or mushrooms per square inch. Type 400 mates to itself, providing maximum strength and engagement. We also offer Types 250 and 170 for a more semipermanent closure where Type 170 mates to Type 400 for less strength. Six different combinations are possible in the Dual Lock^™ family to achieve the ease of release your application requires.

Available in 1/2 in. - 6 in. widths.
Mix and match stem densities for your ideal closure strength.
High level durability; up to 1,000 closure cycles.
Helps reduce vibration.
Temperature, moisture, and UV resistant.
Available in black.
Lightweight and low profile; will not interfere with the integrity of application design.
