Stubby Mag Base
# 309
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. |
