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 a notched head, reverse rulings and stud markings to allow for quick, accurate cuts. The aircraft-style rivets secure the blades for long term accuracy. The head is notched, which enables cutting a 48 in (1219 mm) board in one pass while the board is standing on the floor. You can choose different thicknesses and lengths of the standard drywall T-Square. The handi-square adjustable T-Square is made from durable extruded aluminum and adjusts from 0 to 360 deg. It has one arm which measures 16 in for finding studs and the head is notched, enabling a 48 in board cut in one pass. You can also choose our contractor-grade QLT drywall T-Square.
