APA’s come in a regular and micro size. They have a pre-formed angle of about 40 degrees but are slightly flexible and will adjust to slight angle differences.

The number in the products name corresponds to the spar size that this item will fit, so this fitting is a good choice for a spar with a .157" / 4.00mm outside diameter. Some catalogs refer to this as an "Y" size.

This is our most popular leading edge fitting.
