Sokkia B1-LS70-80 Rod Mounting Bracket
The Sokkia B1-LS70-80 (part number 1030678-01) is the purpose-built rod mounting bracket designed to secure Sokkia and Topcon LS-80L and LS-80X laser receivers to direct-reading grade rods. Engineered for contractors who rely on precise, repeatable grade checks throughout the workday, this bracket eliminates the frustration of constant re-clamping by providing a smooth-sliding rail interface that lets your detector glide freely along compatible LaserLine and Sokkia grade rods. Whether you are setting final grade on a site pad, pulling pipe to grade, or checking subbase depth across a large pour, the B1-LS70-80 keeps your receiver locked on target and your crew moving efficiently.
Overview & Jobsite Applications
Grading operations demand quick height adjustments without stopping to wrestle with hardware. The B1-LS70-80 bracket is machined from lightweight, corrosion-resistant aluminum and features a dedicated rail channel that matches the rod profile on Sokkia and compatible LaserLine grade rods. The result is a single-handed slide-and-lock workflow that saves time on every rod setup. Designed to maintain a rigid, vibration-free connection between the receiver and the rod, this bracket keeps the LS-80L or LS-80X detector perfectly plumb so elevation readings stay accurate from the first stake to the last.

Job Applications
Site Grading & Earthwork: Mount your LS-80L or LS-80X to a grade rod and walk the site quickly, sliding the receiver to the target elevation and checking cut/fill without stopping to re-clamp each time you move.
Pipe & Drainage Installation: Set the bracket to invert elevation on the grade rod and maintain consistent slope checks as you lay pipe in the trench, keeping the detector at a stable reference height throughout the run.
Concrete Flatwork & Subbase Prep: Use the bracket to verify subbase depth and finish grade elevation at multiple points across a slab area, relying on the rigid clamp to hold the receiver level on uneven terrain.
General Construction Layout: Pair the bracketed receiver with any rotating laser level to establish benchmark elevations for footings, forms, or structural fill, taking advantage of the smooth slide to reposition quickly between shots.
