TrigJig BB350 Big Sliding Bevel

• Product: TrigJig BB350 Big Sliding Bevel

• Target Trade: Timber Framers, Steelworkers, Commercial Builders, Joiners

• Core Innovation: A massive 660mm wingspan paired with a custom stainless steel and brass pivot mechanism for locking heavy-duty structural angles.

• Best large-scale sliding bevel for heavy timber and steelwork, eliminating layout drift over extreme lengths.

The TrigJig BB350 Big Sliding Bevel delivers absolute layout precision for heavy timber framing and structural steelwork. Manufactured entirely in-house in England, this behemoth layout tool features a massive 660mm wingspan and a 350mm CNC-machined aluminium tongue. By abandoning standard friction locks in favor of a custom-designed stainless steel and brass pivot mechanism, the BB350 guarantees a rock-solid, zero-drift lock when transferring steep angles across large-scale commercial materials.

The Pro's Equation: Eliminating Drift on a Massive Scale

In heavy timber and box section steelwork, a fraction of a degree in layout drift translates directly to catastrophic material waste and hours of costly rework. Standard sliding bevels simply lack the reach and locking strength required for this scale of structural framing. The TrigJig BB350 solves this vulnerability completely. Featuring an extra-thick 10mm lower body to reference flawlessly against bullnose edges, and a rigid 6mm tongue that doubles as a quick circular saw guide, it accelerates your workflow while providing impenetrable accuracy. With integrated bubble vials and on-tool measurement noting, this is an uncompromising, lifetime business asset that protects your premium materials and your profit margins.

Why Pros Choose the TrigJig BB350:

• Massive Capacity: The 350mm tongue and 660mm total wingspan easily handle large timber and heavy steelwork.

• Zero-Drift Pivot Lock: A custom stainless steel and brass mechanism guarantees angles won't slip during transfer.

• Structural Referencing: An extra-thick 10mm lower body ensures the tool sits perfectly square against rounded or chamfered edges.

• Multi-Tool Efficiency: The rigid 6mm aluminium tongue is thick enough to double as a precision circular saw guide.

• On-Board Calculations: Features a unique white space for jotting measurements directly onto the tool with a pencil.

Can the TrigJig BB350 be used as a circular saw guide?

Yes. The BB350 features a heavy-duty 350mm CNC-machined aluminium tongue that is 6mm thick. This robust construction provides a perfectly rigid and stable edge, allowing professionals to use it directly as a quick circular saw guide on the job site.

Will the pivot lock slip when transferring angles on large structural timber?

No. Transferring large angles requires immense locking friction. The BB350 utilizes a custom-designed stainless steel and brass pivot mechanism that clamps the massive tongue rock-solid, ensuring absolute zero-drift when moving from the layout phase to the cutting station.

Is the tool body thick enough to reference against rounded materials?

Yes. The tool features an engineered asymmetrical body with a 6mm upper section and an extra-thick 10mm lower section. This 10mm lower body provides a secure, stable reference edge even when pressed against materials with a bullnose or heavy chamfered edge.
