Overview

Magnesium construction is the headline spec on the Marshalltown 143D, a 16 inch masonry trowel with a cushioned DuraSoft handle. Magnesium blades resist rust and stay lighter in hand than steel across a full day of finishing concrete or mortar.

Trowel length and blade material do most of the work in this category: a 16 inch magnesium blade covers more surface per pass than the shorter trowels common in the line, while staying corrosion resistant compared with plain steel. The DuraSoft handle is Marshalltown's cushioned grip, aimed at reducing hand fatigue on long pours.

  • 16 inch magnesium blade
  • DuraSoft cushioned handle

Who it's for

Fits concrete finishers, masons and DIY slab pourers who want a full-size finishing trowel rather than a pointing or margin trowel. Less suited to tight corner work or small patch repairs where a smaller blade is easier to control.

Pros and cons

Pros
  • 16 inch blade covers more surface per pass
  • Magnesium resists rust on damp jobsites
  • Cushioned DuraSoft grip for long finishing sessions
Cons
  • Softer than steel, dents under heavy pressure
  • Not sized for tight corner or patch work

Performance notes

Magnesium blades glide over wet concrete with less drag than steel and will not leave rust marks on a cured slab if left outside, though they are softer and can wear faster under rough use. The DuraSoft handle is built to cut vibration transfer during repetitive troweling motions.
