There is a slight 15° bend so that this bracket can be bolted directly to a flat surface and leave room for webbing wrapped into it. It can be sewn in, or wrapped with an LV4 (recommended), LV10 or LV11. FIA and SFI 16.1/16.5 approved. Cannot be used for a Lap Belt bolt-in bracket under SFI 16.5. 3" webbing must be folded at the edges for use with this bracket.
