WWWWL-512-B - Flat Soapstone Marker Holder with Pocket Clip

Technical Specifications and Operational Utility

The WWWWL-512-B Flat Soapstone Holder is a precision-engineered accessory designed to enhance the functionality and durability of standard flat soapstone markers in industrial applications. Constructed from formed steel with a corrosion-resistant plating, this holder provides structural rigidity that prevents the brittle fracture of soapstone sticks—a common issue when stones are used bare or carried in pockets. The unit is specifically dimensioned to accept standard flat soapstone inserts (typically 1/2" wide x 3/16" thick), ensuring broad compatibility with consumable replacements available in the MRO market.

Functionally, the holder features a friction-based or tab-locking thumb slide mechanism. This allows the operator to precisely index the exposed length of the soapstone, providing support close to the marking tip to prevent snapping under pressure. This is particularly critical when marking on rough surfaces such as cast iron, rusted steel, or mill scale, where significant pressure is required to leave a visible trace. The flat profile of the body serves a dual purpose: it prevents the tool from rolling on non-level surfaces, and it provides a flat reference edge that can be used against straightedges for consistent marking angles.

Key Technical Features:

• Body Material: Stamped and formed steel for impact resistance.
• Retention Mechanism: Integrated spring-tension clip ensures the stone does not retract inadvertently during use.
• Portability: A riveted or integrated steel pocket clip allows for secure attachment to PPE, including heavy leather welding gear.
• Heat Resistance: Unlike plastic markers or wax crayons, the all-metal construction and natural soapstone consumable allow for marking on pre-heated materials without melting or off-gassing contaminants that could cause weld porosity.

This tool is an essential component for non-destructive layout work. Soapstone marks are easily removed after fabrication and do not introduce carbon or other contaminants into the weld pool, making them superior to graphite pencils for stainless steel and aluminum applications. The SSHF holder ensures that the welder can maintain a sharp, usable edge on their marking medium, facilitating precise fit-ups and reducing rework caused by poor layout visibility.
