What type of holes is a box patch used for?

A box patch is specifically designed for use on holes that have jagged edges protruding inward. This type of damage creates irregularities that require a patch to effectively seal and provide structural support. The box patch technique involves creating a patch that is fitted around the uneven contours of the hole, ensuring a secure and stable closure.

When dealing with jagged edges, traditional patches may not adhere properly or provide a complete seal. The box patch can be tailored to conform to the shape of these edges, making it particularly effective for repairing this kind of damage. Properly implemented, a box patch prevents water intrusion and helps to restore the integrity of the surface, which is essential in damage control situations.

Other types of holes mentioned in the choices would typically require different patching methods, which are not suited for dealing with the unique challenges presented by holes with jagged edges.
