Standard hook types available:
Tall Palm-Tree Hooks (HTH-66, HTH-31, HTH-36, HTH-24)
High strength, limited closure life cycles. Typically used in automotive and heavy industrial applications where initial holding power is essential and the closure will not be cycled too many times after it has been engaged. Best used with robust, high-pile woven loops such as Loop 1000.

J-Hooks (HTH-15, HTH-22, HTH-29)
These hooks look like an inverted J-shape, or a cresting ocean wave. J-Hooks are designed to offer a good balance between holding strength and cycle life.
HTH-15 Hook – Provides excellent strength and closure cycle life when engaged with Loop 1000.
HTH-22 – A lower profile version of HTH-15. Best used with medium pile knit loops such as Loop 3610 and Loop 3008.
HTH-29 – A very low profile micro-hook with over 1700 hooks per square inch. The hooks are so tiny that you need a microscope to see them. Use this micro hook with non-woven materials and low pile knit loops, such as NWL3310 and Loop 3905.
Packaging Closure
A special polyethylene version of HTH-29 and film backed Loop 3200, this closure is easily heat sealed onto polybags using standard bag-making equipment, to create a touch closure that is easier to open and close that traditional “zipper” style bags. Ideal for packaging fruits, small parts, courier envelopes, and shipping documents.
