What are you making?

T-squares establish a straight reference across a drawing or work surface. Choose among Lance T-squares by construction, head, blade length, blade width, and duty.

Drafting triangles provide fixed angle systems for layout and drawing. Choose the 30°/60°/90° or 45°/45°/90° geometry, then select the required size and template function.

Straight edges support measuring, marking, drawing, cutting guidance, and layout. Choose by unit system, backing, calibrated edge, width, length, and working context.

Pattern-drafting curves help develop controlled contours that a straight rule cannot produce. Choose by the type of contour and the curve geometry needed for the work.

L-squares establish perpendicular layout and support pattern drafting. Choose full-scale or half-scale workflow and confirm both arm dimensions and unit system.

Specialty rulers solve defined measuring and layout jobs, including cuff marking, center finding, and agate or pica measurement. Start with the task, then choose the configuration.

Black engraved rules are selected by unit system, calibrated edge, reading direction, and length. Orientation should be chosen from the operator's working position.

A configured T-square family whose material, head construction, calibration, and physical specifications remain blocked pending first-party verification.

Heavy-duty T-squares use a 2-inch-wide aluminum blade and a 16-inch green ABS head.

Standard T-squares use a 1.5-inch-wide aluminum blade and a 9-inch blue ABS head.

The family uses 30/60/90-degree geometry, one-sixteenth-inch calibration on one edge and one side, and 20 or 26 circular template holes depending on size.

The family uses 45/45/90-degree geometry, one-sixteenth-inch calibration on one edge and one side, and 20 or 26 circular template holes depending on size.

English/metric straight edges place millimeters-to-centimeters on the top edge and inches in sixteenths on the bottom edge, on one side.

Metric straight edges are calibrated on two edges on one side, with millimeters-to-centimeters on the top edge and centimeters on the bottom edge.

Inch straight edges are calibrated on two edges on one side, normally in eighths and sixteenths.

Cork-backed inking rulers are calibrated on two edges on one side in eighths and sixteenths.

French curves are calibrated on one edge on both sides.

Hip curves are calibrated on one edge on both sides.

Standard L-squares are calibrated in inches or centimeters; each arm is calibrated on two edges on one side and one edge on the reverse.

Half-size L-squares are half scale versions of standard L-squares and are calibrated on one edge on two sides.

Cuff rulers are used to mark trouser cuffs of different lengths and widths.

A zero point sits at the center of the top edge with equal measurements left and right in thirty-seconds; the bottom edge is a standard rule in sixteenths.

Agate/Pica rules are intended for layout of printed material and are calibrated on two edges on both sides.
