The MARSHALLTOWN T-Squares come in different styles. The Standard and Metric Drywall T-Squares are made with a silver anodized finish and black epoxy paint numerals for long wear and legibility. They have reverse rulings, and stud markings to allow for quick, accurate cuts. The aircraft-style rivets secure the blades for long term accuracy.
