- The FID 50 is used in thin insulating boards from 1.96 inches (50mm). The FID 90 is used in thicker insulating boards, and can bear higher loads.
- The geometry of the FID allows for a simple installation in thin layers of plaster, without the need for pre-drilling, thus saving a stage of installation.

Bought these an a far cheaper alternative to the tanking manufacturers recommended fixings (about a third of the price). Easy to use and worked just as well.
