From the manufacturer:
Ampersand Floaterframes are designed for wood panels but also work with canvas. They offer an elegant option for displaying artwork, and are an easy all-in-one frame for the DIY artist. Made from quality hardwoods, these professional quality frames feature a wide base to eliminate damage to wood panel cradles and the correct profile height to protect artwork corners. Counter-sink holes allow hanging artwork to be flush with the wall. The frames are available in two styles: Thin Edge (1/4" face) and Bold Edge (3/8" face) in three finishes (Maple, Black and White). Thin Edge frames come in 1-1/4" and 1-1/2" deep profiles for both 7/8" and 1-1/2" deep artwork. The Bold Edge frames come in 1-7/8" deep profiles for both 7/8" and 1-1/2" deep artwork.
