Various embodiments of a frame (200) for attaching an adjunct (220) to an end effector of a surgical device are provided. In one embodiment, the end effector can include upper (202) and lower jaws, and the frame can include features (210) for releasably engaging one of the jaws. The frame can also include retaining features (222) for coupling an adjunct to a tissue-facing surface of the frame, thereby releasably coupling the adjunct material to the jaw of the end effector. In some implementations, the frame can include a plurality of retaining features (222) that are configured to engage the adjunct material (220) to create a tension in the adjunct material, which can further assist with securing the frame to the jaw. In other embodiments, a removable applicator member (360) is provided for retaining at least one adjunct material and for aligning and coupling the adjunct material to a frame.
