The Woodpeckers Cal-Zilla 49 Woodworking Rule combines the accuracy and readability of a Woodpeckers Woodworking Rule with the functionality of a large-capacity caliper. Designed for measuring both internal and external dimensions, it eliminates the guesswork often associated with long measurements by providing positive contact points at both ends of the measurement.

Based around a 1,257mm (49-1/2) Woodpeckers Woodworking Rule, Cal-Zilla offers measuring capacity up to approximately 1,168mm (46). Precision-machined caliper jaws attach directly to the rule, allowing accurate inside and outside measurements across a wide range of workshop applications. The sliding jaw glides smoothly on low-friction UHMW strips and locks securely without damaging the anodised rule surface.

The inside measuring tips correspond directly with the outside jaws, making Cal-Zilla particularly useful for transferring dimensions and checking mating components. Included hole-centre attachments fit to the measuring jaws, allowing accurate centre-to-centre measurement between holes, a common requirement when fitting hardware and laying out projects.

The dual-scale layout features metric graduations on one edge and imperial graduations on the other, both referencing the same datum point for straightforward measurement. A wall-mountable Rack-It is also included, keeping the tool protected and readily accessible in the workshop.

Woodpeckers is known for precision woodworking tools, measuring equipment and workshop accessories designed to improve accuracy and repeatability. Their tools are precision machined and carefully inspected in Ohio, USA.

Ideal for furniture makers, cabinetmakers, engineers and woodworkers who need accurate long-range inside, outside and hole-centre measurements. Supplied with: Woodpeckers Cal-Zilla 49 Woodworking Rule, caliper jaws, hole centre attachments and wall-mountable Rack-It.
