Stubby Mag Base

Dottie CPT1309 Stubby Mag Base

The Checkpoint Stubby Mag Base is designed to be kept on the instrument "full-time" highlighting a strong compact configuration, super strong mag-ratio, and layout versatility in both US and MM. This super high performing compact 9" x 1" version uses four neodymium rare-earth magnets, has Imperial (U.S.) and metric scales laser engraved for layout aid, V-groove ends for centering, 1/4-20 tripod tapped hole for versatility, two counter-bored holes for permanent mounting on repeatable slide in slide out applications for all the 600 and 880 series laser levels. Fully machined and anodized, this quick handling super strong compact also accommodates the Slope Pin System to set exact slope and grade positive or negative.

The Slope Pins attach under either end of the base as indicated on the base sides and are held in place by the neodymium magnets centered on the flat side. They give exact slopes or grades with no calculation depending on your choice of slope pin size. For example, simply place a 1/4” slope pin at the front or rear location of the Stubby or Magnum base, and the 8-80 will project an exact 1/4” per foot rise or fall depending on the location of the pin (+ or -). Slope Pins are sold either individually or in sets of seven pieces, and come in 1/16” increments (starting with 1/8” slope). Again, each will work with all new Mag Bases and the 3D DMS series.
