Spacing gauge for molding and trim

A gauge providing for the accurate marking of peripheral molding and trim prior to cutting said molding and trim for installing said molding and trim adjacent to the peripheral edges of a jointed framed opening in a structure, said gauge comprising;

• a first plate and a second plate formed as a single unit,
• said first and said second plates each respectively having an inner and an outer surface and having an included angle of 90 degrees between said inner surfaces and a common edge therebetween,
• said first plate having two corner edges extending from said common edge,
• said second plate having a setback edge opposite said common edge and two spacing edges therebetween,
• at least one said spacing edge and said setback edge having a common corner defining a setback corner,
• a securing arm pivotally and frictionally attached to said first plate and arcuately pivotable in the same plane as said first plate,
• said securing arm having a distal end including a catch thereby defining an included space between said catch and said second plate, whereby
• said gauge is placed upon said framed opening with one said first plate corner edge abutting said frame joint and said gauge common edge positioned along said frame edge periphery with said setback corner defining an inner corner for said marking of said molding and trim,
• said gauge frictionally and removably held in position by means of said arcuately pivotable securing arm distal catch and said second plate gripping said frame in said space provided therebetween.
