Overview for Spectra Precision 1237 Metal Invert Plate (Centering Plate), Metric
The Spectra Precision 1237 Metal Invert Plate is designed to enhance the setup of lasers on flat surfaces where the laser beam may not be perfectly centered within the pipe. This heavy-duty trivet plate allows for precise elevation adjustments of the laser beam, ensuring accurate measurements regardless of the initial positioning.
Key Features
- Adjustable Elevation: Allows for accurate elevation adjustments by measuring from a grade offset hub outside the trench or from the manhole floor to the laser beam.
- Metric Version: This model is a metric version of the invert plates, with a similar imperial version available as the 1230.
- Self-Centering: Features one-piece cast aluminum construction that provides automatic self-centering of the laser in pipes with diameters of 10 inches (250 mm), 12 inches (300 mm), or 15 inches (400 mm).
- Versatile Use: Ideal for use with the 1239 Universal Fixed Pole for setups in manholes, on manhole bottoms, or in pipes larger than 15 inches (400 mm) in diameter.
Benefits
The Spectra Precision 1237 Metal Invert Plate ensures accurate and efficient laser setups by providing a stable, self-centering platform for the laser. Its robust construction and versatile design make it suitable for various applications, including manholes and large diameter pipes. By allowing precise elevation adjustments, it improves measurement accuracy and setup efficiency in challenging conditions.
Usage Instructions
To use the Spectra Precision 1237 Metal Invert Plate, place the plate on the flat surface where the laser will be set. Adjust the elevation of the laser beam by measuring from the grade offset hub or the manhole floor to the beam, ensuring proper alignment. The plate’s self-centering feature will help position the laser accurately within the pipe diameter.
