OEM Rod Bracket Built for Topcon LS-80 Series and LS-B10 Laser Receivers
The Topcon Holder 6 (part number 312890112) is a genuine OEM rod bracket engineered specifically for contractors running Topcon LS-80A, LS-80B, LS-80G, LS-80L, and LS-B10 laser receivers. When you're grading a pad, cutting a swale, or setting pipe on a tight deadline, the last thing you need is a receiver shifting on the rod. The Holder 6 delivers a rigid, repeatable mount that keeps your receiver locked in position shot after shot, eliminating the guesswork that comes with improvised or aftermarket solutions.
Product Overview and Jobsite Applications
Designed with the working contractor in mind, the Topcon Holder 6 clamps securely to standard grade rods and survey staffs used across earthmoving, utility, and site preparation work. The bracket's Topcon-engineered geometry positions the LS-80 series or LS-B10 receiver at the correct orientation for reliable laser beam detection, whether you're running a single-grade rotating laser across a large grading site or using the LS-B10 for machine control elevation checks. The sturdy construction handles repeated attachment and removal across the job cycle without loosening or wearing out the mounting interface on your receiver.

Job Applications
Site Grading and Earthwork: Mount your LS-80 series receiver to a grade rod for single-operator grade checking across large cut-and-fill areas. The Holder 6 keeps the receiver stable as you move the rod across uneven terrain.
Utility and Pipeline Work: Use the Holder 6 to position your LS-B10 or LS-80 receiver on a grade rod when setting pipe to grade. Consistent receiver positioning means consistent invert elevations without repeated double-checking.
Foundation and Slab Layout: When you need to verify sub-base elevations before a pour, the Holder 6 keeps your receiver exactly where it needs to be on the rod so grade calls are fast and accurate across the slab footprint.
Landscaping and Finish Grading: For fine grading and drainage work where blade passes are tight, a stable receiver mount reduces re-shots and keeps the crew moving efficiently from stake to stake.
