The TrigJig SG38 Aluminium Stair Gauge Set delivers flawless layout repetition while strictly protecting your high-end measuring tools. Crafted from premium T6 6082 aluminium, these gauges abandon the destructive metal-tipped bolts found on standard models.

The Pro's Equation: Speed and Asset Protection

In professional framing and stair building, repeatability dictates your profit margin, but standard gauges often ruin the very squares they attach to. The TrigJig SG38 solves this costly problem. By integrating a non-marking tip, it preserves the readability and lifespan of your expensive precision squares. Furthermore, the smart 1-2 turn locking mechanism drastically reduces setup time. The large, knurled knobs allow professionals to lock and unlock the gauges instantly, accelerating the layout of complex stair stringers and repetitive rafter cuts while eliminating layout drift.

Why Pros Choose the TrigJig SG38:

• Non-Marking Soft Tip: Specially engineered bolts securely grip the square without leaving scratches or gouges.

• Rapid Deployment: A 1-2 turn locking mechanism ensures lightning-fast adjustments on the job site.

• Premium Construction: CNC-machined from T6 6082 aluminium for extreme durability at a minimal weight.

• Slip-Free Grip: Oversized knurled knobs provide maximum torque, preventing the gauge from sliding mid-layout.

• Universal Fit: Seamlessly attaches to all standard commercial framing and rafter squares.

No. The TrigJig SG38 is specifically engineered with a non-marking soft tip on the stainless steel bolt. This ensures that you can clamp the gauges tightly against your premium anodized squares without leaving any scratches, dents, or wear marks.

How fast is the locking mechanism compared to traditional gauges?
