Sokkia 1030679-01 DE Rod Bracket for LS-100D Topcon Receiver B1-LA

Sokkia B1-LA Aluminum Rod Bracket for Laser Receivers

The Sokkia 1030679-01 B1-LA rod bracket is a professional-grade aluminum mounting accessory designed to keep laser detectors securely positioned on direct-reading grade rods while allowing fast, tool-free vertical repositioning throughout the workday. For field crews running high-volume grade checks on earthwork, utility, or paving sites, the B1-LA eliminates the frustrating cycle of loosening and re-tightening a fixed clamp every time the receiver needs to move — shaving real minutes off every setup and reducing cumulative fatigue across a full shift.

Overview & Jobsite Applications

Engineered from extruded aluminum, the B1-LA is built to withstand the daily abuse of active construction environments — mud, vibration, repeated handling, and temperature swings — without adding unnecessary weight to the rod. The bracket's sliding channel design keeps the receiver upright and properly oriented on the rod face so the detector window always faces the rotating laser beam. Whether you're setting pipe grades, checking subbase elevation, or shooting finished floor heights, the B1-LA keeps your workflow moving without interruption.

Frequently Asked Questions

What laser receivers is the Sokkia B1-LA rod bracket compatible with?

The B1-LA is primarily designed for the Sokkia and Topcon LS-100D laser receiver but is also compatible with the Topcon LS-80L, Apache, CST Berger, and select Leica laser detectors. Always confirm your receiver's mounting dimensions against the bracket specs before ordering.
