A system for measuring fence posts in a fence run includes a leading unit and a trailing unit. The leading unit includes a first measurement wire extending through a first rotary encoder and terminating in a second rotary encoder, a second measurement wire terminating in a third rotary encoder, and a third measurement wire terminating in a fourth rotary encoder, as well as a clamp to secure the leading unit to a fence post. The trailing unit includes a first rotary encoder to engage with the first measurement wire of the leading unit and a measurement wire terminating in a second rotary encoder, as well as a clamp to secure the trailing unit to a fence post.

A pipe laser device is attached to plumbing that will be added to or extended to show the angle and direction of where the existing plumbing is pointing so the installer knows precisely where to drill to accommodate the new plumbing. The pipe laser has an adaptor/connector that can fit inside an existing plumbing pipe to attach the pipe laser device to the existing pipe. The device has an emitter (laser diode) within the device that delivers the beam (laser beam) from the opposite end of the device. The laser diode is centered on connector that sits within the existing pipe, and so allows the laser beam delivered from the other end to also be centered relative to the existing pipe. Thus, the beam from the opposite end can precisely indicate where on an opposing wall the opening should be created for the existing plumbing to continue through that wall.

A method and apparatus for lifting loads support from a crane to eliminate swaying of the load includes providing the crane with a laser source on either side of the crane. The center of gravity of the load is marked on the load and the boom is positioned such that the laser lights projection on the ground or on surface of the load and the center of gravity of the load are aligned in a straight line.

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.

A water line mapping assembly includes a remote unit that is held by a user. The remote unit has a remote transceiver that is in electrical communication with a global positioning system (gps). A capsule is provided that has an outside diameter sufficiently small to fit into a buried pipe. The capsule is comprised of a buoyant material to float in the buried pipe, and the capsule is comprised of a fluid impermeable material. A tracking unit is positioned inside the capsule and the tracking unit is in wireless electrical communication with the gps. Thus, the gps can establish a depth and a position of the tracking unit when the capsule is positioned in the buried pipe. The tracking unit is in electrical communication with the remote unit thereby facilitating the remote unit to display the depth and position of the tracking unit. In this way the remote unit can map the buried pipe.
