Helix - Plastic T-Square - 18" - 45cm - Lightweight and Versatile

Happy with my t square ruler. Nice item fast shipping

I wanted a small T-square for a traveling drawing board (masonite), and I needed about 14". Of course, I can shorten this one much better than lengthening a 12" one.It's transparent blue, and I'd have preferred clear, but I knew what I was ordering from the description.I like it.

Problem #1: The cheap plastic has considerable flex and therefore has trouble staying square.Problem #2: Instead of a small rabbit in the edge for no-smudge inking, it has two raised tracks running down the middle of the ruler, which keep it standing off the work. It is not very stable, and allows the ruler to rock forward and back easy. Some of my drafting triangle want to slip under the ruler if I am not careful.Problem #3: The same tracks in the middle hold the T head above the drafting board, causing drafting triangles to catch on it and not be able to slide beyond the edge of the drafting board.Who designs this garbage?I recommend purchasing a Minerva or Graphoplex. They are well made with a quality acrylic. They are not widely available in the US, but you can go on the UK Amazon site and order them.

Functionally, it gets the job done but a metal or wooden T-square would have been better for me. This one squirms.

other than the length of time for delivery, the product is okay. it is simple plastic t-square that meets my needs.

Sturdy T Square.

Love this for my acrylic paintings

Just what I wanted.

Excellent
