Kapro Tools Offers 930 SmartCast Heavy-Duty Mason’s Level with OPTIVISION™ Red Leveling Technology

Words: David BenincasaKapro Tools’ 930 SmartCast Heavy-Duty Mason’s Level with OPTIVISION™ Red leveling technology provides unmatched clarity for a number of applications, including tile setting and concrete work.

Features of the 930 SmartCast Heavy-Duty Mason’s Level include:
  • OPTIVISION Red horizontal vial
  • Tilted, tri-surface horizontal vial
  • Bridge at horizontal vial
  • Heavy-duty cast aluminum tapered body
  • Shock-absorbing rubber strike pads and end caps
Kapro’s patented OPTIVISION vial features an easy-to-read vial bubble with super defined edges and strong surrounding color definition, as well as an extra set of reading lines for setting gradients at 1 and 2 percent. The OPTIVISION Red’s unique epoxy-locked tilted setting offers a direct line of sight to the bubble, which makes reading the vial easy and provides more precise results.

The high contrast ratio between the red bubble and vial liquid in Kapro’s solid acrylic vials makes visibility up to eight times easier than clear liquid vials with white backgrounds. OPTIVISION provides superior visibility in low and bright light and is UV-resistant, meaning the vial always maintains its original color contrast and visibility.

“Kapro’s patented RedEffect™ is a proven attention-getter on the worksite,” said Gal Wollach, vice president of business development at Kapro Tools. “In addition to standing out in the toolbox, Kapro’s industry-leading OPTIVISION products deliver more precise leveling results in the high-quality, durable construction professionals seek.”

Kapro’s OPTIVION series levels are certified as conforming with their stated accuracies of <0.0005 in/in, the highest in the industry, by the German VPA Laboratory which provides official international verification of their high accuracy and quality. Kapro’s solid acrylic vials carry a lifetime warranty, guaranteeing them for the highest level of accuracy as well as against leakage or breakage.
