Factory installed permanent pin system. When concrete forms are outfitted with attached hardware, wedging is only required at top and bottom pin. Available on 36" to 9" fillers, however, most contractors typically have it installed on 36" wide concrete forms only.
On 108" concrete forms, most contractors do not utilize the top hole for a tie, therefore, many choose to place an attached pin which will aid in alignment - by simply engaging the pin.
The New FastLock Attached Hardware System
FastLock Attached Hardware System is retractable for use with loose pins. It has a rotational ball that allows for auto stowing for faster stripping. FastLock has a low maintenance housing, rust resistant coating, and a hardened nose that eliminates mushrooming. FastLock has a larger lead-in and loop that helps in stripping and also acts like a spring so it maintains its shape while eliminating the need for use of a wedge.
