The Butler 7051 Manhole Mount gives sewer and storm drain contractors a rigid, field-proven platform for plumbing a transit or optical instrument directly over a pipe laser inside a manhole. When you need to transfer line and grade from one manhole run to the next — especially around curves, elevation changes, or when shooting through multiple intermediate structures — the 7051 delivers the precise, plumbed setup that keeps your alignment on target and your crew moving efficiently.
Overview & Jobsite Applications
Designed to seat securely across standard manhole frames, the Butler 7051 eliminates the improvised setups that waste time and introduce error. The mount positions your instrument directly over the pipe laser below, allowing accurate line transfer without requiring a second instrument or a separate setup at grade. It's the go-to solution for contractors running sanitary sewer, storm drain, or combined sewer systems where maintaining grade continuity through each structure is non-negotiable.

Job Applications
Sanitary Sewer Installation: Transfer line and grade through intermediate manholes on long runs, keeping pipe alignment consistent from structure to structure without resetting your laser from grade.
Storm Drain Construction: Maintain accurate alignment through curved or offset manhole runs where a direct laser shot between inlet and outlet is not possible.
Rehabilitation & Inspection Projects: Use the 7051 to re-establish control points inside existing structures when verifying or correcting grade on aging sewer systems.
Multi-Structure Runs: On projects with multiple intermediate manholes, the 7051 allows crews to leapfrog line transfer efficiently, reducing total instrument setup time across the project.
