Kapro 105

Kapro 105 Topgrade Gradient Box Level is an all-surface leveling tool. This level features a printed table of equivalence with percentage, gradient, pitch and mm/m for accurate measurements. This box level features vials that are pre-installed at 0%, 1% and 2% sloping (The 48" version has 2 additional vials at 0.5% and 1.5%) as well as a vertical plane. Instead of using gradient vial lines, it has a separate vial for each slope – Level, 0.5%, 1%, 1.5% and 2%.

The Kapro 105 is perfect for serious DIY’ers and handymen. Use these Topgrade levels for tiling, concrete, plumbing, and construction! The Kapro 105 Topgrade has sturdy, rubberized end caps, solid acrylic vials with an accuracy of 0.0005"/" and a very high quality milled surface.

At Kapro, we reimagine precision tools and accessories for professional craftsmen to weekend warriors while setting high standards by driving innovation in our designs.

What does the lifetime vial accuracy warranty cover?

The lifetime vial accuracy warranty covers the part of your vial, not the whole level.

Please note that only solid acrylic vials are covered under the lifetime warranty. Cylindrical vials are covered for 1 year - frame damage voids the warranty.

Should your vial fail due to factory defect, Kapro will either replace the level or offer MSRP value in the form of a coupon to use here on ShopKapro, depending on availability - discontinued items are not eligible for exact replacement.

The warranty does not cover damage to the level from misuse, abuse, or accidental damage.

Should the vial fail due to frame damage, warranty is voided.

If my frame is damaged, will it be covered under warranty?

No, the lifetime vial accuracy warranty only covers the part of the vial for factory defects.

Frame or milled surface damage from misuse, abuse, or accidental drops and falls void the warranty on the vial.

Are cylindrical vials covered under the lifetime vial accuracy warranty?

No, cylindrical vials are only covered under a 1 year limited warranty - Frame damage voids warranty.
