The stretcher is the arrangement of brick laid with its length parallel to the face of the wall. A course that contains a stretcher is called a stretcher bond.

7. Header in Masonry

The header is the arrangement of brick laid with its breadth or the width parallel to the face of the front direction of the brick or stone masonry wall.

Bricks laid with its longer sides vertical are called soldiers. A course with soldiers is called a soldier course. This provides visual interest to the masonry structure. It is a type followed in brick masonry.

9. Arrises in Brick Masonry

The edges formed by the intersection of the faces of the bricks are called the arises. The arises formed must be sharp, clean and free from damage.

10. Perpends in Brick Masonry

The perpends are vertical joints that separate the brick unit either lengthwise or cross-direction wise. In order to achieve good perpends, the vertical joints in alternative courses must be one above the other.

11. Lap in Brick Masonry

Lap is defined as the horizontal distance between the vertical joints in successive courses. A lap length of one-fourth brick length is said to be a good lap in brick masonry.

12. Closer in Brick Masonry

A closer is defined as a piece of brick that is used to close up the bond at the end of the brick masonry course. This helps to prevent the formation of vertical joints of successive courses in a single line. Closer need not be specially molded.

13. Queen Closer and King Closer in Masonry

A queen closer is obtained by cutting the brick longitudinally in equal parts. This can also be made from two-quarter bricks which are designated as quarter closers. This helps to minimize wastages in masonry construction.

King closer is obtained by cutting a triangular portion of the brick. This on laying provides half header and half stretcher on the adjoining cut faces. Near the door and window openings a king closer is used, so that mortar joints can be provided with proper arrangement.

14. Bat in Brick Masonry
