In brick masonry, identify the piece cut such that one corner equals half the length and half the width of a full brick (used to maintain proper bond at quoins and junctions).

Introduction / Context:
Bond in brickwork relies on specially cut units to break continuous vertical joints and maintain interlock. Among these, closers are used at the ends of courses (quoins). This question asks you to recognize which cut brick has one corner equal to half the length and half the width of a standard brick—an important detail in English and Flemish bonds.

Given Data / Assumptions:

• Standard modular brick dimensions are assumed.
• Terminology: king closer, queen closer, bevelled closer, etc.
• Application: maintaining quoin bonding and joint staggering.

Concept / Approach:
A king closer is formed by cutting off a triangular portion from a brick so that at one end the width is half and at the adjacent face the length is also half; in effect, at the corner, the dimensions correspond to half-length and half-width. A queen closer is cut longitudinally into two equal halves (half the width across the full length).

Step-by-Step Solution:
Recall definitions: queen closer = longitudinal half; king closer = triangular cut producing half-length and half-width corner.Match the description to the definition: the described piece is a king closer.Select “King closer.”

Verification / Alternative check:
Standard masonry references show king closers placed next to quoin headers to maintain alternate bonding.

Why Other Options Are Wrong:

• Queen closer: only half-width along full length, not the described triangular corner.
• Bevelled closer: cut at an angle but not forming half-length and half-width at the corner.
• Half king closer: nonstandard term in most specifications.
• Half bat: cut across length; different application.

Common Pitfalls:
Confusing queen closer (longitudinal half) with king closer (triangular cut for quoins).

Final Answer:
King closer
