Alvin PXB Drafting Board with Parallel Bar Comparison Sheet vs Martin Universal & MacPherson Drafting Boards

  • PXB aluminum straightedge has soft, rubber grip edges for enhanced comfort and control.  Theirs only have ridges.  The rubber grip is much better for lifting the blade over drawings to prevent smudging
  • PXB board has a large, comfortable carry handle with rubber grip.  Theirs have small, plastic handles
  • PXB adjustment knobs are made from hard rubber and generously sized for comfort and control.  Their knobs are made from plastic and steel, and some have sharp uncomfortable edges
  • PXB acrylic blade is 2.5 mm thick and includes inking edges to minimize smudging.  Their blades are only 1.5 mm thick and do not have inking edges
  • PXB straightedge can travel within ¼” of the top and bottom edges of the board.  This maximized usage of the entire board surface.  Their straightedges can only get within 3/4" of the top and bottom edges
  • PXB straightedge has two brake mechanisms, one on each end, for secure, positive locking.  Theirs have only one brake
  • PXB wire capture knobs under the board have built-in screw stops to prevent the knobs from falling off accidentally.  Their knobs have no stops and are frustrating to reassemble when they come apart
  • PXB 3 largest have long, folding legs for a better working angle.  Their boards use the same short legs for all sizes.
  • PXB won't scratch the table it's placed on because it rests on 4 rubber feet.  Their boards rest on bare metal when used in the flat position
  • PXB board thickness is 16 mm for all 6 PXB sizes.  Their thickness is only 12 mm, which is more fragile and easier to break
  • PXB blade has fine tune adjustment knobs on both sides.  Theirs have only 1 knob for fine tuning.
