Disclosed is a leveler that is able to bring two or more tiles it is in contact with to the same level.

Disclosed is a leveler that is able to bring two or more tiles it is in contact with to the same level.

For leveling tiles, a tile leveler includes a base, a plurality of joint spacers, and two or more break lines. The brake lines are formed in the base along planar axes. Each joint spacer is within a subdivision distance of a break line. Each joint spacer adjacent to a given break line is on a spacer side of the given break line, and the break lines divide the base into sections.

A leveling clip and tile leveling device for use of the same are disclosed. In one embodiment, the leveling clip includes a body defining an opening that is configured to accept a wedge device thereat. Tapered legs extend from the body and join a base at a base to body coupling. The base extends to a front and a rear of the body. The base to body coupling includes a frangible breakaway section that is integral prior to frangible separation and the frangible breakaway section, upon breaking, frangibly separates the body from the base. The leveling clip may be used with the wedge device to install two, three, or four tiles.
