Technical Data

Product Description

July, 2009

3M? Dual Lock? Low Profile Reclosable Fasteners SJ4570 and SJ4575 can

replace conventional fasteners, such as screws, clips, rivets, snaps, hook and loop

and bolts in many applications where access or repositioning is needed. Dual Lock

low profile reclosable fasteners consist of continuous strips of plastic backing, with

tiny plastic mushroom shaped stems protruding up from the backing strip. When

two pieces of 3M? Dual Lock? Low Profile Reclosable Fasteners are pressed

together, the “mushroom heads” interlock with one another creating an audible

snap, indicating the fastener is engaged. The Dual Lock low profile reclosable

fastener is thinner allowing it to be more flexible than similar reclosable fasteners.

The Dual Lock low profile reclosable fastener SJ4570 is a clear fastener offering

transparent properties to allow color and patterns to visibly show through giving the

fastener an almost invisible appearance. The Dual Lock low profile reclosable

fastener SJ4575 is black in color and gives a definite presence for when you want to

see your fastener or have it blend in with a dark background. The Dual Lock low

profile reclosable fasteners offer intermediate strength between regular 3M? Dual

Lock? and 3M? Scotchmate? Reclosable Fasteners, with all of the advantages of

a self-mating product.
