A fenestration installation diagnostic system includes a diagnostic cord and a plurality of diagnostic fittings configured for coupling with a fenestration assembly. Each of the diagnostic fittings includes at least one bracket leg configured to statically couple the diagnostic fitting with the fenestration assembly and at least one alignment interface, and the alignment interface is configured to align the diagnostic cord at a diagnostic intersection. Each of the diagnostic fittings further includes at least one cord guide configured to route the diagnostic cord along the diagnostic fitting and toward another diagnostic fitting of the plurality of diagnostic fittings. In a diagnostic configuration with the fenestration assembly each of the diagnostic fittings are statically with the fenestration assembly, and the diagnostic cord tautly extends from the alignment interfaces of the plurality of diagnostic fittings to the diagnostic intersection.

The inventive concept presented is a trench slope angle tool and the method for using the slope angle tool during the excavation of a trench in a particular type of soil. In essence the slope angle tool is a planar, hand-held sighting device having a handle integrally attached to a Y-shaped component. The device may be utilized by a construction worker or project supervisor (the user) at a trenching worksite. The user visually superimposes the slope and banks of the trench against the contours of the slope angle tool to determine compliance with government-regulated excavation standards. Other important construction safeguards and govemmentally-regulated standards are also displayed on each face of the slope angle tool. In this manner, the correct trench sidewall slope, spoil pile locations, and other safety requirements can be readily observed to determine whether these elements are in compliance with the governmental regulations.
