1/2" Stage Fixture Field Template is one of the flagships of the Field Template™ Family. Not only does it provide you with information about each kind of lighting instrument, it eliminates the need for scale rules and other drafting tools, reducing the time required to draft a 1/2" scale light plot. The patented PRO•TRAK 50 System aligns the symbols onto horizontal axes (so you're not having to shift the template up and down to trace different instruments). The bold vertical lines are 1’-6" apart (So all the symbols are the same distance apart). The scaled rulers on the top and bottom of the template are reversed (So you don't have to flip the template around like a lasso to measure distances left and right from centerline. The Grid•Dots are located at 45° around each symbol (So you can trace instruments at matching 45° angles without a triangle). The 1/2" Stage Fixture Field Template™ also provides safety and unit information: Hanging weight (stage weight symbol) Cut color size (folded-back Post-it symbol) Beam spread information is listed under each symbol.
