Topcon Holder-110 Rod Bracket

Keep your Topcon LS-100D digital laser receiver mounted securely and positioned correctly on the grade rod with the factory-designed Topcon Holder-110 Rod Bracket (part number 1019505-01). This is not a generic aftermarket clamp — it is the OEM mounting solution engineered by Topcon specifically for the LS-100D, delivering a precise, repeatable fit every time you clip it to the rod. For contractors, surveyors, and grading crews who depend on the LS-100D day in and day out, this bracket is the reliable connection between your receiver and your work.

Overview & Jobsite Applications

The Holder-110 rod bracket is designed to clamp onto standard grade rods and story poles, holding the LS-100D at the operator-selected height while providing stable signal capture from rotating laser levels. The purpose-built mounting geometry aligns the receiver's detection window at the correct angle and height, reducing the risk of missed grade calls or signal interference caused by improper mounting. Whether you're grading a pad, setting forms for a foundation, or laying pipe to grade, a secure and accurate receiver mount is just as important as the receiver itself. Worn, broken, or ill-fitting brackets introduce slop into the system and undermine the precision your laser equipment is built to deliver.

Job Applications

Site Grading & Earthwork: Mount the LS-100D to a grade rod and let the Holder-110 keep it locked in position as your operator walks cuts and fills. A secure bracket means the receiver stays at the set grade height without shifting between readings.

Foundation & Footing Layout: When setting forms to an exact elevation, the last thing you need is a bracket that slips or wobbles. The Holder-110's OEM fit ensures the LS-100D reads consistently from shot to shot, keeping your form elevations tight.

Utility & Pipeline Work: Pipe layers running grade by laser depend on repeatable receiver positioning. The Holder-110 keeps the LS-100D at the correct rod height throughout the run, supporting accurate invert and grade control.

General Construction Layout: From floor flatness checks to elevation transfers, any task that puts the LS-100D on a rod benefits from a bracket that holds it where you put it — the Holder-110 does exactly that.
