Details

Here is the corrected text: This product features a hollow wooden sounding box measuring 1290 x 130 x 110 mm (length x width x height). The box is equipped with scales marked in millimeters between fixed bridges, over which the wires are stretched. It comes complete with three movable bridges, a wrist-pin key, and a set of four wires, each 1.5 meters long and available in 20, 22, 24, or 26 SWG gauges. The distance between the fixed bridges is 720 mm (approximately 47" x 4.75" x 5.25"). One wire features a spring balance that reads up to 100N with 5N increments, allowing for fine adjustments of tension using a wing nut. Another wire passes over a pulley and can be loaded as desired. A third wire is provided for comparison purposes, with its tension adjustable via a wristpin. The supplied wires are made of rust-resistant steel. Weights are not included.
