New, laser projection system from SL-Laser. Projects roof truss, floor truss and wall panel design images accurately onto building surface, for faster setup and fabrication times. Each laser head provides 21' projection length (@15 foot ceiling heights). Includes system computer, cables, mounting hardware for attachment to customer's structure, factory installation, training and choice of green or red laser. Works with each connector plate manufacturer's design software. Modular nature of the laser heads allows for easy, future expansion of system length. 120 volt, 1 phase.
