PRODUKTDETAILS
The L-Shape Holder for MP110D Double Side Mini Prism is a specialized mounting accessory engineered for deformation monitoring and high‑precision surveying. Its L‑shaped geometry provides a fixed 90° angle, essential for offset measurements and control network establishment.
Manufactured from premium stainless steel, the holder resists weathering, vibration, and mechanical stress – key requirements for railway and infrastructure projects. The integrated clamp design allows it to grip rail profiles securely without damaging the surface, while the prism mounting socket accepts the 25.4 mm MP110D double‑side mini prism (either copper‑coated for enhanced reflectivity or silver‑coated for cost‑effective applications).

Every holder is CNC‑machined to tight tolerances, ensuring that the mounted prism’s center coincides exactly with the L‑bar vertex. This geometric precision, combined with the prism’s 3‑4 arcsecond accuracy, delivers repeatable, trustworthy readings even under dynamic loads or temperature fluctuations.
L-Shape Holder for MP110D Double Side Mini Prism Use Cases / Application Scenarios
Railway Track Displacement Monitoring – Clamp the holder directly onto the rail web or base to track lateral/vertical movement over time.
Bridge Deformation Surveys – Fix the L‑shaped holder to steel girders or abutments for periodic total station measurements.
Tunnel Section Control – Install along tunnel walls to monitor convergence and settlement during construction or operation.
Landslide & Slope Stability Projects – Mount the holder on inclinometer casings or concrete pillars for long‑term prism‑based monitoring.
Industrial Alignment Tasks – Use on crane rails, conveyor structures, or heavy machinery guides where 90° reference targets are required.
