Lufkin L12CS Speed Square 12 Inch Aluminum

Product Description

The LUFKIN L12CS is an aluminum speed square designed for layout, marking, and angle checking on job sites and in shop environments. With a 12-inch blade length and a base measuring 3 inches in both length and width, it provides a stable reference surface for consistent scribing and squaring tasks. The blade width measures 4.75 inches, and graduation is marked at 1/32-inch (0.0313 inch) increments for precise measurement. The aluminum construction keeps the tool lightweight at 0.67 pounds while maintaining rigidity under daily trade use. No bevel edge is present on this model. HVAC technicians, plumbers, electricians, carpenters, and sheet metal workers reach for this style of square as a standard layout instrument.

The L12CS fits residential and commercial construction and service work wherever straight-line marking, rafter layout, or perpendicular checking is required. It is well suited for ductwork layout, framing checks, conduit marking, and general material scribing. The compact base and full 12-inch blade make it practical for both bench work and in-field use where a full framing square is too large. A single unit is packaged per order with no minimum order requirement above one piece.

Installation Notes

No power source or shutoff is required for this hand tool. Keep the base edge clean and free of debris before referencing it against a workpiece to maintain measurement accuracy. Inspect the blade and base for bends or damage before use, as a deformed square will transfer measurement error to finished work. Handle aluminum layout tools with care around abrasive surfaces to preserve graduation legibility over time.
