Product details:
The GR1000I 10' Laser Lenker Style direct reading level rod, gradations in feet/inches, allows you directly observe the true elevation of any point on the job site without any performing any calculations. Designed for use with a laser level and receiver (it has a track to allow the receiver to slide up and down the rod), the GR1000I can also be used with an optical level. NOTE: A special LaserLine detector bracket is required to attach your laser receiver to the rod. For Spectra Precision HL450 & HL700 receivers use the LLB-STORM bracket. For Topcon LS-80 receivers use the LLMB1LS70-80 bracket. Other receivers can use the LLMUB-1 Universal Bracket. All are available separately. Simply set the reading on the rod to match the elevation of a known elevation such as a benchmark or hub. This is possible because the rod face is actually a continuous flexible tape mounted on rollers within the frame of the rod which can be locked down once set. From then on, every elevation reading around the job site can be read directly by noting where the pointer of your laser detector is when you get the on gradesignal, or through your optical level. FEATURES: The Laser Line GR1000I Direct Reading grade rod is made of high strength clear anodized aluminum for lightweight rugged, dependable operation. It will not rust, split, splinter swell or warp in any environment. The tape has a heavy duty matte textured face which is easy on the eyes in bright sunlight and protects the tape numbers from wear and fading. Tape lock grommets are over sized, heavy duty brass. This greatly minimizes the problem of tape tearing. Detector rail is black, high density, U.V. stabilized for long life. It is specifically designed to not become brittle when exposed to ultraviolet rays or direct sunlight. The solid tape lock has an internal brake slide for stronger, trouble-free operation.
