Abstract

A multiple-hole rope thimble with a body, a plurality of holes, and a perimeter groove. The holes can be arranged linearly or non-linearly arranged and can be the same or different sizes. The hole wall is curved toward the center of the hole to eliminate any sharp edges that can damage a rope. The groove extends completely around the perimeter of the body. A rope fits into the groove and is secured around the thimble by a splice or a knot. Optionally, the rope is secured by a thread extending through an aperture in the partition between holes.
