Rosewood 6" Try Square - Double Brass Faced - Trial 1 Series by Joseph Marples of Sheffield, England |
|
This Square has a blade that is 6" long and 2" wide. The base of the square is 4-5/8" long, 1-3/4" wide and 3/4" thick. The square represents the very best quality produced by Joseph Marples of Sheffield, England. The design is based on tools last made over 70 years ago, which carried the "TRIAL 1" Corporate Mark.
The squares have 1/8" thick machined brass on both the inside and outside faces, thus ensuring accuracy on the inside and outside edges. They have a chemically blacked spring steel blade, secured to the Rosewood stock with brass diamond washers and steel rivets. The accuracy of the try squares is well within that required by BS3322 with a guaranteed tolerance of less than 0.0005" per inch over the entire length of the blade. Made in Sheffield, England.
