What it is and who it's for

The 3M SJ4575 Dual Lock Low Profile fastener is a 2 in. x 10 ft. black reclosable strip that replaces screws, rivets or hook-and-loop in applications needing thin, flexible attachment. It suits makers, exhibitors and installers mounting panels, graphics, ceiling tiles, seat cushions or small electronic devices where repositioning is required.

What to check before ordering

The acrylic 300 LSE adhesive bonds well to polypropylene, polyethylene, metal and finished wood, but surface energy varies by substrate so test adhesion on the actual material first. The roll is a single continuous strip; typical use cuts it in half to create two mating 5-foot pieces, so plan the cut layout before applying.

What the bundled items change

The 86# polycoated Kraft release liner protects the adhesive until installation and peels away cleanly, while the 65-mil carrier-plus-adhesive thickness keeps the profile low enough for tight clearances such as E-ZPass tags on windshields. No separate hook or loop components are included because the fastener mates with itself.

Questions about this item

Does the 10 ft roll of 3M SJ4575 include a mating strip or do I need to buy a second roll?

The roll is a single 10 ft length of identical mushroom-head material; you cut it in half to create two 5 ft strips that interlock with each other, so no separate mating roll is required.

Should I choose the 65 mil low-profile version or a thicker Dual Lock for a 4575 model?

SJ4575 is the low-profile variant at 65 mils total thickness (carrier plus adhesive), making it thinner and more flexible than standard Dual Lock while still using the same 300 LSE acrylic adhesive.

What does the 300 LSE acrylic adhesive rating mean for bonding to polypropylene or metal?

300 LSE denotes a high-performance acrylic formulated to bond securely to low-surface-energy plastics such as polypropylene and polyethylene as well as to metal and finished wood.
