Poly-Lock™ Plastic Tape Fasteners
PolyLock® Plastic Tape Fasteners

5 to 11 Times Stronger Than Hook & Loop

Poly-Lock® Brand Plastic Tape Fasteners provide a quick, easy, self-locking reclosable fastening system for a variety of applications that need a strong and super durable hold. Fasteners do not require precise alignment to provide secure closure.

Poly-Lock is available in black or clear and with the following grids: 170, 250 and 400. This number refers to the number of mushroom heads per square inch. Type 170 has 170 stems per square inch and so on. The higher the number, the stronger the hold. The 400 grid Poly-Lock is recommended for more permanent uses. The 250 grid Poly-Lock is recommended for everyday use around your house, garage or business.

Replace unslightly, troublesome mechanical parts using fasteners constructed of polyolefin stems with mushroom shaped tops. Use to secure frequently removed parts where tensile strength is required such as: access panels, signs, display components and automobile headliners. Great for many applications instead of hooks, latches, snaps, zippers, dials, screws and more. There are literally thousands of other uses!

Poly-Lock is available in 15' dispenser boxes or 150' rolls. We also offer most of our Poly-Lock in a package with two 4" x 3/4" strips for small jobs.
