Bon Tool 11-771 Convex Jointer 7/8 by 1 Inch R Style

Product Description

The BON TOOL 11-771 is an R Style convex jointer built for masonry finishing work. Machined from high carbon tempered steel, the tool is heat treated for wear resistance and hand polished to a smooth finish. The working profile measures 7/8 inch by 1 inch, making it suited for striking mortar joints to a consistent, uniform radius. Licensed masons and tile setters are the primary installers of this tool, using it during the finishing stage of brick, block, or stone work while mortar is still green.

This convex jointer is used in residential and commercial masonry applications where a rounded, compressed joint profile is required. It fits standard hand-jointing technique and works across a range of brick and block formats. The 7/8-inch by 1-inch R Style profile is a commonly specified size on commercial block work and residential brick veneer projects. Contractors select this size based on mortar joint width and the finished profile required by the project specification.

Installation Notes

This tool is used by licensed or experienced masonry contractors during mortar finishing. Strike joints while mortar has begun to set but is still workable - timing varies by mix and conditions. Clean the jointer regularly during use to prevent mortar buildup that can drag the joint surface. No power tools or mechanical fasteners are required for operation.
