Marshalltown 15524 Brick Jointer 3/4 7/8 Inch Dual-end

Product Description

The MARSHALLTOWN 15524 is a dual-end brick jointer designed for finishing mortar joints in masonry construction. One end forms a 3/4-inch concave joint and the other end forms a 7/8-inch concave joint, giving the mason two common joint profiles in a single tool. Constructed from high carbon steel, the 15524 is built to withstand the repetitive pressure required to compact mortar fully into the joint. Proper compaction seals the joint against moisture infiltration, which is critical to long-term wall integrity. Masonry contractors and bricklayers reach for this tool during both new construction and tuckpointing work.

The 15524 is suited for residential and light commercial masonry applications where standard brick coursing calls for concave jointing. It is used during the tooling stage of brickwork, after mortar has reached thumb-print firmness, to strike and compact joints to a consistent profile. The dual-size format reduces the need to carry multiple jointers on a scaffold or mud board, which is a practical advantage on production bricklaying jobs.

Key Features

• Dual-end design: one end tools a 3/4-inch concave joint, opposite end tools a 7/8-inch concave joint
• High carbon steel construction for durability under repeated striking pressure
• Compacts mortar to resist moisture penetration at the joint face
• Two of the most common brick joint sizes combined in one tool
• Sold individually (unit of measure: each)

Compatibility

Designed as a general-purpose masonry jointing tool suitable for standard brick and block applications requiring 3/4-inch or 7/8-inch concave mortar joint profiles.

Installation Notes

This tool is used by masonry tradespeople during the joint-finishing stage of brickwork. Tool joints after the mortar has stiffened to thumb-print firmness to achieve a clean, compacted profile without dragging or tearing. No power tools or special fasteners are required. Follow applicable masonry standards and project specifications for joint profile requirements.
