The David White SitePRO 32-20080B is a 200-foot heat-treated steel tape graduated in feet, inches, and eighths of an inch — the measurement system that professional contractors, surveyors, and site superintendents rely on for precise layout work. Whether you're establishing building setbacks, verifying property boundaries, or striping a parking lot, this tape gives you the reach and the resolution to get the job done right the first time.
Overview & Jobsite Applications
The 32-20080B is purpose-built for the demands of commercial and residential construction layout. With 200 feet of measuring range, it eliminates the repositioning and cumulative error that comes from stringing together shorter tapes on large sites. The heavy-duty ABS case, reinforced planetary gear rewind, and corrosion-resistant blade are engineered for daily use on concrete, asphalt, and rough graded surfaces — not weekend projects. David White's SitePRO line is an authorized professional grade product trusted by contractors, civil engineers, and layout crews across North America.
Key Specifications

Key Features
- Heat-Treated Steel Blade: Resists kinking, stretching, and corrosion under repeated field use and exposure to moisture and debris
- 3:1 Planetary Gear Rewind: Fast, controlled retrieval that protects the blade from snap-back damage and extends service life
- Ft/In/8ths Graduations: Clear, high-contrast markings in the increments used by framing, masonry, and civil layout crews — no conversion required
- Heavy-Duty ABS Case: Impact-resistant housing survives drops on hard surfaces without cracking or losing calibration
- Ring-Type End Hook: Anchors securely to stakes, pins, or rebar for true one-person layout on open sites
- 200-Foot Range: Covers full building widths, parking lot rows, and property line segments in a single pull
Job Applications
Foundation & Building Layout: Establish batter board lines, verify diagonal dimensions for square, and confirm setbacks from property lines with the precision an eighths-graduated tape provides on large commercial slabs and residential foundations.
Parking Lot Striping & Paving: Lay out stall widths, drive aisle spacing, and ADA-compliant zones across full parking fields without repositioning your zero point. The 200-foot range covers most standard lot rows in a single measurement.
Property Boundary Verification: Cross-check survey monuments and confirm lot dimensions in the field before breaking ground. The heat-treated blade maintains consistent length under tension, critical when measurements are being compared against recorded plat distances.
Utility & Site Grading Layout: Stake out storm drain runs, utility corridors, and rough grade control points on large graded sites where lesser tapes fall short of the required measurement distance.

Frequently Asked Questions
- What does "Ft/In/8ths" graduation mean on this tape?
- The blade is marked in feet, with each foot subdivided into inches, and each inch subdivided into eighths (1/8"). This is the standard graduation for most framing, masonry, and civil layout work in the United States, allowing you to read measurements directly without converting decimal feet or millimeters.
- Is the 32-20080B suitable for surveying use?
- The 32-20080B is a heavy-duty contractor layout tape best suited for building layout, site control, and construction measurement tasks. For precision boundary surveying requiring NIST-traceable calibration or chaining accuracy under tension, a dedicated surveyor's steel chain or calibrated EDM is recommended. That said, many field crews use this tape effectively for site layout and grade control.
- How does the planetary gear rewind work and why does it matter?
- The 3:1 planetary gear rewind multiplies your handle-cranking speed, so 200 feet of tape retrieves quickly without overworking the mechanism. More importantly, the geared system provides controlled, smooth retrieval that prevents the blade from snapping back under tension — a common cause of blade kinking and premature wear on cheaper open-frame reels.
- Can I use this tape in wet or muddy conditions?
- The heat-treated steel blade is corrosion-resistant and designed for outdoor use, but like all steel tapes it should be wiped clean and allowed to dry before storage to prevent rust and blade stiffness. Avoid leaving the tape extended in standing water or coiled while wet for extended periods. Routine blade lubrication with a light machine oil will significantly extend service life in harsh field conditions.
