What should be used to ensure a frame is secured in position during installation?

Using shims is essential during the installation process to ensure that a frame is secured in position. Shims are thin, wedge-shaped pieces used to fill gaps or spaces between objects, helping to align and stabilize them. When installing doors, windows, or other frames, shims are typically placed behind the frame to adjust its height, level, and plumb orientation. This is particularly important in construction, as it helps to prevent any future settling or movement that could cause misalignment or operational issues.

While nails are commonly used to fasten components together, they do not provide the same level of adjustability that shims do during the initial installation. Glue may provide adhesion, but it does not allow for adjustments once set. Wire, though useful in certain fastening applications, does not serve the purpose of leveling or stabilizing a frame. Thus, shims are the optimal choice for ensuring a frame is properly secured and aligned during installation.
