The term "jamb cleat" refers to a type of metal bracket used in woodworking to fix a panel to a structure such as a door jamb. The term is pronounced /dʒæm kli:t/ in IPA phonetic transcription, with the first syllable pronounced as "jam" and the second as "kleet". The word appears to have originated in the 19th century, likely from the combination of "jamb" (the vertical side of a doorway), and "cleat" (a strip of wood or metal used to strengthen or support).
A jamb cleat is a type of hardware used in construction and carpentry to secure and reinforce doors and windows within their surrounding frames, also known as jambs. It is typically made of metal, such as steel or aluminum, and is designed to provide additional strength and stability to the jamb structure.
The jamb cleat consists of a flat, elongated plate with multiple mounting holes along its length. One side of the cleat is securely fastened to the jamb, either through screws or bolts, while the other side extends outward to create a perpendicular surface.
The purpose of the jamb cleat is to prevent the deformation or warping of the jamb caused by external forces or pressure, such as the weight and movement of the door or window. By securely attaching the cleat to the jamb, it helps distribute the load evenly and reinforces the structural integrity of the opening.
This hardware component is particularly useful in heavy-duty applications or in situations where the jamb is exposed to increased stress or constant use. It provides added support and prevents any sagging or misalignment that could occur over time.
The jamb cleat is an essential element in carpentry and construction projects, playing a crucial role in maintaining the functionality and longevity of doors and windows within their frames.
The word "jamb cleat" does not have a clear, specific etymology as it is a compound term made up of two separate words.1. Jamb: The word "jamb" comes from Old French "jambe", meaning "leg" or "post". It entered Middle English in the 14th century as "jamb" with the specific sense of the vertical side of a doorway or window frame. Over time, "jamb" has come to refer to the vertical supporting members on either side of an opening.2. Cleat: "Cleat" comes from Old English "clēat", which means a "strip of wood". It is derived from the Proto-Germanic word "klauto", meaning "hook" or "peg". The term "cleat" generally refers to a piece of metal, wood, or other material with projections, often used for fastening or attaching objects.
