The Leica 746162 is a single aluminum pipe laser foot engineered for use with the Leica Piper 100 and Piper 200 pipe lasers in 8-inch diameter pipe applications. Precision-matched to the internal radius of 8-inch pipe, this foot maintains correct invert contact to eliminate rocking and keep your grade laser locked on target. Whether you're replacing a damaged foot or adding a second foot for improved stability on long runs, the 746162 delivers the consistent, dependable support that underground utility and sewer contractors demand on every shot.
Overview & Jobsite Applications
Stable pipe laser positioning is non-negotiable when every tenth of a percent of grade matters. The 746162 foot mounts directly to the Leica Piper chassis and contacts the invert at the geometrically correct arc for 8-inch pipe, preventing lateral shift that can throw a grade shot off before work even begins. Contractors use this foot for new sewer main installation, storm drain grading, force main directional boring checks, and pipe rehabilitation inspection setups where precision instrument placement is required on a specific pipe diameter.
Key Specifications
- Part Number: 746162
- Compatible Instruments: Leica Piper 100, Leica Piper 200
- Target Pipe Diameter: 8 inches (200 mm)
- Quantity: Single foot
- Construction: Aluminum body with rounded rubber base pad
- Function: Invert-contact stabilizer foot for pipe laser
- OEM Part: Yes — genuine Leica replacement component
Key Features
- Radius-matched base: Curved aluminum profile is sized precisely for 8-inch pipe ID to ensure full, stable contact at the invert
- Rounded rubber pad: Absorbs minor surface irregularities and prevents metal-on-pipe sliding during setup
- Aluminum construction: Lightweight yet durable — resists corrosion in wet sewer and storm drain environments
- Direct OEM fit: Mounts to standard Leica Piper foot attachment points with no modification required
- Single-foot configuration: Ideal as a replacement unit or as a supplemental foot when working in non-standard setups
- Compact form: Easy to carry as a spare in any instrument case or tool bag
Job Applications
New Sewer Main Installation: Set grade shots in 8-inch PVC or concrete sewer main with confidence that the laser won't shift between setups, keeping your pipe layers on grade from manhole to manhole.
Storm Drain & Culvert Grading: Use the 746162 foot in 8-inch CMP or HDPE storm drain lines where precise invert elevation control is required to meet design flow velocities and avoid ponding.
Pipe Rehabilitation & CCTV Staging: When positioning a Piper laser for pre- or post-rehabilitation grade verification inside an existing 8-inch line, the correct foot radius keeps the instrument centered and the beam true.
Replacement After Field Damage: Rubber pads and aluminum feet take abuse in active construction environments. Keeping a spare 746162 on the truck means a cracked or missing foot never shuts down a grade operation mid-shift.

Frequently Asked Questions
- Will the Leica 746162 foot fit the Piper 100 and the Piper 200?
- Yes. The 746162 is a genuine Leica OEM component compatible with both the Piper 100 and Piper 200 pipe lasers. It mounts to the standard foot attachment points on both instruments without any modification.
- Why does pipe diameter matter when selecting a laser foot?
- Each foot is curved to match the internal radius of a specific pipe size. Using a foot sized for a different diameter means the base won't sit flush against the invert, allowing the instrument to rock and introducing grade error. Always match the foot to your actual pipe ID.
- Is this listing for a single foot or a pair?
- This listing is for a single foot only. If your application or instrument configuration requires two feet, you will need to order two units of the 746162.
- Can I use this foot in pipe materials other than concrete, such as PVC or HDPE?
- Yes. The rubber base pad on the 746162 provides grip and stability on smooth-wall pipe materials including PVC, HDPE, and ductile iron, as well as rougher surfaces like concrete and vitrified clay, as long as the internal diameter is 8 inches.
